PRODUCTION AND OPERATION DURING THE REPORTING PERIOD

1.    OVERALL OPERATION

      The Group is principally engaged in the production and sale of petroleum
      products, petrochemical, organic chemical and synthetic rubber products.

      During the first half of 2005, the Company implemented a strategy of
      vertical integration in refinery to improve and adjust its overall product
      mix; closely monitored the development of product market and took full
      advantage of any price movement of products so as to adjust its product
      sales strategy in a timely manner; continued to improve efficiency, save
      energy and reduce wastage for the purpose of imposing stringent control on
      costs and expenses; continued to improve internal control to enhance
      capital management and increase efficiency in the use of capital.

      For the first half of 2005, the sales revenue and sales of the Company and
      its subsidiaries (together "the Group") amounted to RMB16,122.195 million
      and RMB17,992.634 million, respectively, under PRC GAAP and IFRS,
      representing the increase of 28% and 31% from the same period in 2004. The
      continuing substantial increase in the price of crude oil drove the price
      of refined oil to move upward, which unfortunately failed to offset any
      impacts caused by price rise in crude oil. Actual realized net profits and
      profits of the Company were RMB123.957 million and RMB135.030 million,
      respectively, down by 80% and 77% as compared to the corresponding period
      in 2004.

2.    OPERATING REVENUES AND PROFITS FROM PRINCIPAL BUSINESS ACTIVITIES

      For the first half of 2005, in accordance with PRC GAAP, actual realized
      revenue from the sale of the Group's petroleum products was RMB7,589.622
      million, which accounted for 47% of the revenue from principal business
      activities and the requisite cost of sales was RMB8,519.813 million, with
      a gross profit margin of -12%; actual realized revenue from the sale of
      petrochemical and organic chemical products was RMB7,315.044 million,
      which accounted for 45% of the revenue from principal business activities
      and the requisite cost of sales was RMB5,544.427 million , with a gross
      profit margin of 24%; actual realized revenue from the sale of synthetic
      rubber products was RMB878.241 million, which accounted for 5% of the
      revenue from principal business activities and the requisite cost of sales
      was RMB706.814 million, with a gross profit margin of 20%.

3.    The Company conducts its principal business in the PRC and does not engage
      in any other industry other than the petrochemical industry. During the
      reporting period, there was no change in the Company's principal business,
      nor was the Company engaged in any other business which had material
      impact on its net profits during such reporting period.


                                  Page 6 of 32


4.    During the reporting period, no jointly-invested company had an impact of
      more than 10% on the net profits of the Company.

5.    PROBLEMS AND DIFFICULTIES IN THE OPERATION OF THE COMPANY

      For the first half of 2005, the continuing substantial increase in the
      price of crude oil drove the price of refined oil to move upward, which
      unfortunately failed to offset any impacts caused by price rise in crude
      oil. As a result, the Group recorded a loss from the sale of its petroleum
      products, thereby adversely affecting the overall performance of the
      Company. For the first half of 2005, net profits of the Company decreased
      by 80% as compared to the same period in 2004.

OPERATING RESULTS AND FINANCIAL RESULTS ANALYSIS

I.    UNDER PRC GAAP

      1.    For the six months ended 30th June 2005, revenue realized from the
            principal business of the Group was RMB16,122.195 million, an
            increase of 28% from the same period in 2004. This increase was
            principally attributable to an increase in the total number of
            products of the Group, such as petroleum products, petrochemical,
            organic chemical and synthetic rubber products, and the increase in
            their price.

            (1)   PETROLEUM PRODUCTS

                  In the first half of 2005, revenue from the sale of petroleum
                  products was RMB7,589.622 million, an increase of RMB1,157.868
                  million from the same period in 2004. The increase was
                  primarily attributable to an increase in the volume of the
                  Group's crude oil processing by 16% from last year to 3.5
                  million tons in the first half of 2005. In addition, the
                  weighted average price of petroleum products grew by 16% from
                  RMB2,416/ton in the first half of 2004 to RMB2,798/ton in the
                  first half of 2005.

            (2)   PETROCHEMICAL AND ORGANIC CHEMICAL PRODUCTS

                  In the first half of 2005, revenue realized from the sale of
                  petrochemical and organic chemical products was RMB7,315.044
                  million, representing an increase of RMB2,252.693 million from
                  the same period in 2004. This increase was principally
                  attributable to an increase in the demand of petrochemicals
                  from enterprises engaged in the downstream segment of the
                  petrochemical industry, which has resulted in the sales volume
                  and weighted average price of such products increasing by 16%
                  and 25%, respectively, from the same period in 2004 to 1.07
                  million tons and RMB6,841/ton.

            (3)   SYNTHETIC RUBBER PRODUCTS

                  In the first half of 2005, revenue realized from the sale of
                  synthetic rubber products was RMB878.241 million, an increase
                  of RMB154.964 million from the same period in 2004. The
                  increase was principally attributable to an increase in the
                  weighted average price of such products by 24% from the same
                  period in 2004.

      2.    The cost of principal business increased by 38% to RMB15,123.413
            million in the first half of 2005 from RMB10,955.477 million in the
            first half of 2004. This increase was principally attributable to a
            growth in the sales volume of the Company's products and the volume
            of crude oil processing, as well as an increase in the price of
            other raw materials. In the first half of 2005, the weighted average
            price of the Group's crude oil cost was RMB3,016/ton, which
            represented an increase of 47% as compared to the same period in
            2004.

            The cost of sales grew due to the continuing substantial increase in
            the price of crude oil. Therefore, profits of the Group from its
            principal business dropped by 52% as compared to the same period in
            2004.

      3.    Financial cost, administrative and operating costs decreased by 35%
            from RMB548.128 million in the first half of 2004 to RMB357.736
            million in the first half of 2005, of which, the financial cost
            decreased by RMB67.410 million from the same period in 2004. This
            decrease was primarily due to a reduction in the Group's interest
            bearing borrowings and the replacement of the Company's
            high-interest bearing loans with low-interest bearing loans. As a
            result, interest expenses decreased by RMB58.083 million. The Group
            realized a net exchange gain of RMB12.197 million due to its foreign
            currency borrowing being affected by the interest rate fluctuation.
            Administrative expenses decreased from RMB382.719 million in the
            first half of 2004 to RMB267.197 million in the first half of 2005.
            This decrease was principally due to the provision of RMB76.870
            million made for the decrease in inventory price and the provision
            of RMB22.533 million made for bad debts in the same period in 2004
            which were not made during the current reporting period.

            In the first half of 2005, the Group recorded a loss from other
            business activities and its profits from operation fell by RMB57,733
            million.

            Due to the above factors, the Group's profits from its operation
            decreased from RMB647.149 million in the first half of 2004 to
            RMB174.272 million in the first half of 2005.

      4.    Compared to the first half of 2004, the Group's return from
            investment decreased by RMB2.166 million in the first half of 2005
            due to a reduction of the Group's share of profits of its jointly
            controlled entity. The decrease of RMB56.186 million in
            non-operating expenses of the Group was principally attributable to
            no substantial loss incurred in the disposal of fixed assets during
            the reporting period. In addition, revenue from subsidies and
            non-operating revenue increased by RMB8.199 million.


                                  Page 7 of 32


            Based on the aforesaid, the Group's total profits decreased from
            RMB592.302 million in the first half of 2004 to RMB181.643 million
            in the first half of 2005.

            In the first half of 2005, the income tax of the Group amounted to
            RMB51.192 million, which consists of the deferred tax liabilities
            arising from the acceleration of depreciation and amortization, and
            the deferred tax assets resulting from taxation loss in the first
            half of 2005. In the same period in 2004, the Company did not make
            up in full its accumulated loss for 2002 and the previous years in
            accordance with applicable taxation laws and no deferred tax assets
            in respect of such taxation loss had been confirmed. Therefore,
            there was no income tax in the same period in 2004. In addition, the
            minority interest of the Group was RMB6.494 million during the
            reporting period. After deducting the above, the Group recorded a
            net profit of RMB123.957 million in the first half of 2005.

      5.    Net increase in cash and cash equivalents amounted to RMB25.671
            million in the first half of 2005, and net decrease in cash and cash
            equivalents amounted to RMB19.221 million in the same period of
            2004. This change was primarily attributable to the improvement of
            capital management and an increase in the turnover of capital of the
            Company.

      6.    As at 30th June, 2005, the total assets of the Group was
            RMB12,717.874 million, representing a decrease of 12% as compared to
            the percentage as at 31st December, 2004. This decrease was
            principally attributable to a decrease in inventories and an
            increase in accumulated depreciation.

      7.    As at 30th June, 2005, the shareholder's equity of the Group was
            RMB5,977.581 million, representing an increase of 2% from 31st
            December, 2004. This increase was primarily attributable to an
            increase in net profits during the reporting period.

II.   UNDER IFRS

      1.    In the first half of 2005, total turnover of the Group was
            RMB17,992.634 million, up 31% from the same period in 2004. This
            increase was primarily attributable to an increase in market demand,
            thus resulting in the simultaneous increase in the Group's sales
            volume and the weighted average price of its products.

            (1)  PETROLEUM PRODUCTS

                 Revenue of petroleum products increased by 17% from
                 RMB6,212.553 million in the first half of 2004 to RMB7,263.050
                 million in the first half of 2005, which accounted for 40% of
                 its total turnover attributable to petroleum products. The
                 increase in revenue was principally attributable to an increase
                 of weighted average price and sales volume of petroleum
                 products by 16% and 2%, respectively, from the same period in
                 2004.

            (2)  PETROCHEMICAL AND ORGANIC CHEMICAL PRODUCTS

                 Revenues of petrochemical and organic chemical products
                 increased by 45% from RMB5,493.959 million in the first half of
                 2004 to RMB7,943.724 million in the first half of 2005, which
                 accounted for 44 % of the total turnover attributable to such
                 products. This increase was principally attributable to an
                 increase in market demand which has caused an increase of
                 weighted average price and sales volume of petrochemical and
                 organic chemical products by 25% and 16%, respectively, from
                 the same period in 2004.

            (3)  SYNTHETIC RUBBER PRODUCTS

                 Revenue of synthetic rubber products increased by 27% from
                 RMB800.349 million in the first half of 2004 to RMB1,017.254
                 million in the first half of 2005. This increase was mainly
                 attributable to an increase in the price of such products by
                 24% from the same period in 2004.

      2.    Cost and expenditure

            The cost of sales increased by 39% from RMB12,615.949 million in the
            first half of 2004 to RMB17,508.817 million in the first half of
            2005. This increase was primarily attributable to an increase in the
            sales volume of the Company's products, volume of crude oil
            processing and the price of other raw materials. In the first half
            of 2005, the weighted average price of the Group's crude oil cost
            was RMB3,016/ton, which represented an increase of 47% from the same
            period in 2004, and the volume of crude oil processing was 3.5
            million tons, which represented an increase of 16% from the same
            period in 2004.

            The Group's gross profit margin decreased by 5% in the first half of
            2005 as compared to the same period in 2004 due to an increase in
            cost of sales in connection with the continuous surge in crude oil
            price.

            Distribution costs, administrative expenses and other operating
            expenses dropped by 40% from RMB384.770 million in the first half of
            2004 to RMB230.143 million in the first half of 2005. This decrease
            was primarily attributable to the provisions made for diminution in
            value of trade and other receivables, construction in progress and
            intangible assets made in the first half of 2004 which were not made
            during the reporting period, a net loss of RMB34.158 million
            incurred from the retirement of fixed assets in the first half of
            2004 and a net profit of RMB4.638 million so incurred during the
            reporting period.

            Due to the aforesaid factors, the Group's operating profit decreased
            from RMB729.256 million in the first half of 2004 to RMB253.674
            million in the first half of 2005.

            Interest expenses decreased by 38% from RMB152.934 million in the
            first half of 2004 to RMB94.851 million in the first half of 2005.
            The decrease was principally attributable to a reduction in the
            Group's interest bearing borrowings and the replacement of
            high-interest bearing loans with low-interest bearing loans during
            the reporting period.


                                  Page 8 of 32


            In the first half of 2005, the Group recorded a net foreign exchange
            gain of RMB12.197 million, which increased by RMB9.1 million from
            the same period in 2004. This increase was mainly attributable to
            the foreign exchange rate fluctuation in favour of the Company's
            foreign currency borrowing during the reporting period.

            In the first half of 2005, the Group's shares of profit before
            taxation of its jointly controlled entity and associate stood at
            RMB11.396 million, as compared to RMB13.564 million in the first
            half of 2004. This change was primarily caused by a decrease of
            profit of its jointly controlled entity and associate during the
            reporting period.

            In the first half of 2005, the income tax of the Group amounted to
            RMB48.209 million, which consists of the deferred tax liabilities
            arising from the acceleration of depreciation and amortization, and
            the deferred tax assets resulting from taxation loss in the first
            half of 2005. In the same period in 2004, the Company did not make
            up in full its accumulated loss for 2002 and the previous years in
            accordance with applicable taxation laws and no deferred tax assets
            in respect of such taxation loss had been confirmed. Therefore,
            there was no income tax in the same period in 2004.

      3.    Liquidity and Capital Resources

            The Company depends upon cash flow from operations and loans to
            satisfy its ongoing liquidity and capital needs.

            Net cash flows from the Group's operating activities in the first
            half of 2005 was RMB2,059.624 million, as compared to RMB1,295.921
            million in the first half of 2004. The increase of net cash inflows
            was primarily due to a decrease in inventories during the reporting
            period.

            Net cash used in investing activities in the first half of 2005 was
            RMB40.426 million, as compared to RMB195.203 million in the first
            half of 2004. This decrease was due to a decrease in capital
            expenditure during the reporting period.

            Net cash used in financing activities in the first half of 2005 was
            RMB1,993.527 million, as compared to RMB1,119.939 million in the
            first half of 2004. The change was due to a decrease in proceeds
            obtained from borrowings during the reporting period.

            As at 30th June, 2005, the Group's current assets amounted to
            RMB2,198.547 million and the current liabilities amounted to
            RMB5,999.173 million, which caused a negative working capital of
            RMB3,800.626 million. The Group regularly reviews its working
            capital and liquidity position and ensures the short term
            obligations of the Group are satisfied through the refinancing of
            indebtedness and other measures. China Petroleum Finance Company
            Limited, a subsidiary of our ultimate beneficial shareholder, has
            agreed to extend the term of a RMB8 billion loan facility provided
            to the Group up to 31st December, 2008. The Company believes that it
            has sufficient capital resources to meet its foreseeable working
            capital needs. As at 30th June, 2005, the Group's capital
            liabilities ratio was 12% as compared to 15% as at 31st December,
            2004 (the capital liabilities ratio is calculated by dividing the
            long-term liabilities by the aggregate of shareholders' equity and
            long-term liabilities).

            As at 30th June, 2005, the Group's liquidity ratio was 37% and its
            quick ratio was 12%; inventory ratio was 7.66 times, an increase of
            0.45 times as compared to the same period in 2004.

            As at 30th June, 2005, the Group's aggregate borrowings were
            RMB1,988.563 million, a decrease of RMB1,993.527 million as compared
            to the figure as at 31st December, 2004, of which short-term
            borrowings was RMB1,268.212 million, representing a decrease of
            RMB1,817.863 million as compared to the level of short-term
            borrowings as at 31st December, 2004. Long-term borrowings were
            RMB720.351 million, representing a decrease of RMB175.664 million as
            compared to the same type of borrowings as at 31st December, 2004.
            These changes reflected an increase in the repayment amounts of the
            Group during the first half of 2005 which in turn led to a decrease
            in liabilities ratio.

            The Group does not have seasonal demands for capital.

      4.    Exchange Risk

            On 30th June, 2005, the Group's short-term borrowings were
            denominated in Renminbi and the portion of long-term borrowings
            denominated in foreign currency that was translated into RMB968.803
            million was mainly a foreign currency-denominated loan for the
            300,000-ton ethylene facility project. Foreign currency-denominated
            loans are mainly taken out in United States Dollar, Japanese Yen and
            Euro Dollar. The Group also experiences foreign exchange risk in
            making payments related to the import of raw materials and
            machinery, which needs to be converted into the applicable foreign
            currency from Renminbi. In addition, dividends for H shares are also
            payable in foreign currency. Hence, any fluctuation in foreign
            exchange rates will have a significant impact on the Group. In the
            first half of 2005, the Group had a net foreign exchange gain of
            RMB12.197 million.

      5.    Employees

            As at 30th June, 2005, the Company had a total of 20,187 employees.
            The aggregate remuneration paid to them was RMB378.110 million.


                                  Page 9 of 32


      6.    Charges of Assets

            The Group has not created any charges on any of its principal assets
            as at 30th June, 2005.

      7.    Contingent Liabilities

            The Group did not have any significant contingent liabilities as at
            30th June, 2005.

INVESTMENT (CAPITAL NOT OBTAINED FROM FUND-RAISING ACTIVITIES)

During the first half of 2005, the Company did not carry out any large-scale
technological renovation projects. The total investment attributable to such
projects was RMB57.174 million as at 30th June, 2005.

PROSPECTS OF THE SECOND HALF OF 2005

For the second half of 2005, the Company will further strengthen the following:
(i) the management of safety production by arranging for installation and
overhaul of equipment so as to ensure its production facilities run at full
capacity; (ii) the control on capital budget in order to use capital in a
safely, reasonable and efficient manner, thereby speeding up the turnover of its
capital; (iii) the control on cost budget by continuing to implement a low-cost
strategy to reduce the production and operation costs; (iv) the marketing
management in order to respond to the changes in petrochemical and chemical
products. The Company expects the processing capacity for crude oil to reach 3.5
million tons in the second half of 2005. In view of the continuing increase in
the price of crude oil to a high level which may not be offset by the increase
in the price of refined oil, the actual realized profits for the period from
January to September 2005 is expected to decrease by over 50% as compared to the
same period in 2004.

13.   HOUSING REFORMS

      Since 1998, the Company has incurred a loss of RMB84.09 million due to the
      discount offered to its employees to purchase staff accommodation.

      In accordance with IFRS, the above loss was capitalized. The staff cost
      associated with the Company's employee housing reform programs was
      amortized on a straight-line basis over the remaining expected average
      employment period of the relevant employees.

      From 1st January, 1998 to 30th June, 2005, the total amount amortized was
      RMB54.55 million. The amount amortized in the first six months of 2005 was
      RMB4.66 million. As at 30th June, 2005, the above remaining deferred staff
      cost was approximately RMB29.54 million. In the opinion of the Board, if
      the aforesaid deferred staff cost was completely written off in the first
      half of 2005, the net assets of the Company as at 30th June, 2005 would be
      reduced by approximately RMB29.54 million. Other than the employees'
      housing reform programs mentioned above, the Company has not implemented
      any employees' housing plan.

      Income tax expense is recognised based on the best estimate of the
      weighted average annual income tax rate expected for the full financial
      year. During the six months ended 30th June, 2005 and 2004 there was no
      current tax expense because of the utilisation of tax loss carryforwards.
      Tax expense during the six months ended 30th June, 2005 results from
      changes in the deferred tax assets and liabilities at the expected annual
      rate of 33%.

      control of the Company (e.g. nature disasters or instability of crude oil
      prices) or the development of new projects, is required to purchase or
      supply additional products and services, then the Company shall, before
      any of the revised annual caps as mentioned above is breached, re-comply
      with the reporting and announcement requirements described in rules 14A.45
      to 14A.47 and the independent shareholders' approval requirements
      described in rule 14A.48 of the Listing Rules for the decision to purchase
      or supply such additional products or services on the basis of any revised
      business plan and comprehensive financial analysis.

2.3   ASSETS MANAGEMENT AGREEMENT

      The Company sells ethylene to Jilin Petrochemical under the Master
      Products and Services Agreement. The production capacity of the Company's
      existing ethylene production facilities is approximately 380,000 tonnes
      per year (the "Existing Facilities"). Due to the increasing demand of
      Jilin Petrochemical for ethylene, which could not be satisfied by the
      Existing Facilities, and the Company's lack of funds to expand such
      production facilities, Jilin Petrochemical carried out an expansion of the
      Existing Facilities. The expanded facilities to the Existing Facilities
      are expected to commence commercial operation around 31 October 2005 with
      an annual production capacity of approximately 220,000 tonnes (the
      "Expanded Facilities").

      To manage and operate the expanded ethylene production facilities in a
      efficient manner, Jilin Petrochemical and the Company entered into the
      Assets Management Agreement on 12 August 2005 under which the Company will
      be responsible for the management and operation of the Expanded Facilities
      owned by Jilin Petrochemical.

      Subject to obtaining the independent Shareholders' approval, the Assets
      Management Agreement will be valid for a term of three years from the date
      of the commencement of commercial operation of the Expanded Facilities.
      The Expanded Facilities are expected to commence commercial operation
      around 31 October 2005. Following the expiry of such three year term and
      in the event that Jilin Petrochemical intends to sell the Expanded
      Facilities upon the expiry of such three year term, the Company shall have
      a right of first refusal upon the same terms and conditions offered by
      Jilin Petrochemical. Jilin Petrochemical shall also procure the third
      party which will acquire the Expanded Facilities to undertake to be bound
      by the Assets Management Agreement. Further announcement will be made if
      the Company acquires the Expanded Facilities according to the Listing
      Rules.

      Following the commencement of commercial operation of the Expanded
      Facilities, of the total amount of the ethylene produced by the Existing
      Facilities and Expanded Facilities as a whole ("Expanded Ethylene Plant"),
      on a monthly basis, 63.33% shall be attributed to the Company and 36.67%
      to Jilin Petrochemical, being the respective percentages of the designed
      production capacity of the Existing Facilities and the Expanded Facilities
      to the total designed production capacity of the Expanded Ethylene Plant,
      i.e., approximately 600,000 tonnes. The costs of ancillary materials,
      public utilities services and fuels consumed by the Expanded Ethylene
      Plant shall also be shared by the Company and Petrochemical according to
      such percentages. The costs pertaining to the fixed assets in relation to
      the Expanded Ethylene Plant such as the costs of depreciation, production
      safety insurance fund and maintenance shall be separately accounted for
      and borne by the Company and Jilin Petrochemical in relation to the
      Existing Facilities and Expanded Facilities, respectively.

      The ethylene and related products produced by the Expanded Ethylene Plant
      attributable to the Company will be supplied to fully satisfy the
      requirements of the downstream production facilities of the Company and
      any excess amount may be sold to Jilin Petrochemical or independent third
      parties. Such ethylene and related products attributable to Jilin
      Petrochemical will be supplied to satisfy the requirements of its
      downstream polyethylene production facilities and any excess amount may be
      sold to the Company or independent third parties.


                                 Page 26 of 32


      The production materials for ethylene produced by the oil refinery
      facilities shall be supplied to fully satisfy the requirement of the
      Existing Facilities and any excess amount (if any) may be sold to Jilin
      Petrochemical to be used for the Expanded Facilities. The Company will
      purchase additional amount of production materials required by the
      Existing Facilities from independent third parties. Jilin Petrochemical
      will mainly purchase the production materials required by the Expanded
      Facilities from independent third parties.

      During the first year following the commence of commercial operation of
      the Expanded Facilities, Jilin Petrochemical shall pay the Company a
      management fee at RMB21 per tonne of ethylene attributable to the Expanded
      Facilities, which is determined by reference to the average amount of the
      labor cost involved in the production of ethylene by the Existing
      Facilities for the two years ended 31 December 2004 and six months ended
      30 June 2005. The amount of the ethylene attributable to the Expanded
      Facilities is estimated not to exceed 260,000 tonnes per year. Such
      management fee will be increased by 15% each year thereafter. The
      management fee is payable on a monthly basis before the 5th day of each
      month.

      As such, the management fee payable by Jilin Petrochemical to the Company
      is expected not to exceed RMB910,000, RMB5,600,000 and RMB6,440,000 for
      each of the three years ending 31 December 2007, respectively.

3. BASIS FOR INCREASING THE CAPS FOR THE CONTINUING CONNECTED TRANSACTIONS

3.1   GENERAL PRINCIPLES

      The Directors consider that it is in the interest of the Group to continue
      the Continuing Connected Transactions upon the same terms and conditions
      set out in the Continuing Connected Transactions Agreements as amended by
      the Supplemental Agreements and the Assets Management Agreement.

      The Directors had revised the annual caps for the Continuing Connected
      Transactions for each of three financial years ending 31 December 2007
      based on the following factors:

      (a)   the Continuing Connected Transactions will continue to be entered
            into between the Company and the relevant Connected Persons upon the
            terms and conditions set out in the relevant Connected Transaction
            Agreement as amended by the relevant Supplemental Agreements and
            Assets Management Agreement;

      (b)   the annual caps are set or revised based on the amounts of the
            Continuing Connected Transactions for the year ended 31 December
            2004 and the six months ended 30 June 2005 set out below under
            paragraphs 3.2.1 and 3.3.1 and for the reasons set out below under
            paragraphs 3.2.3 and 3.3.3;

      (c)   there will be no material changes in existing government policies,
            political, legal, fiscal, or economic conditions in the PRC or
            countries to which the Company exports its products; and

      (d)   there will be no material delay in the production schedule or
            expansion projects of the Company or material changes in the
            production process of the Company.

      The Directors consider that the caps for the Continuing Connected
      Transactions and the basis on which such caps are set or revised are fair
      and reasonable in the interest of the Company and Shareholders as a whole.

                                 Page 27 of 32


3.2.3 The basis and reasons for revising the caps for the Continuing Connected
      Transactions with PetroChina are as follows:

      (A)   PURCHASE OF PRODUCTION MATERIALS

            The price of the production materials purchased by the Company from
            Jilin Petrochemical has increased substantially in line with the
            increase in the market price of petrochemical products in the PRC,
            which tracks an increase in the price of crude oil by approximately
            47% in the first half of 2005. The price of such production
            materials has increased by an average of approximately 40% in the
            first half of 2005 compared with the same period in the last year.
            Such substantial increase is beyond the Director's reasonable
            expectation. The Directors expect an increase of approximately 30%,
            40% and 50%, respectively, in the price of such products for each of
            the years ending 31 December 2007 on a year-on-year basis.

            In order to comply with the new environmental protection standards
            for diesel oil carried out by the PRC government in 2004, the
            cracking diesel oil produced by the Company must be refined through
            the hydrogenation treating facility of Jilin Petrochemical and the
            Company will re-purchase the hydrogenated diesel oil for its further
            processing and sales to Jilin Petrochemical. With the increase in
            the volume of crude oil, the amount of the cracking diesel oil
            produced by the Company which must be hydrogenated through the
            hydrogenation treating facilities of Jilin Petrochemical increased
            accordingly, resulting in a substantial increase in the amount of
            the hydrogenated diesel oil purchased by the Company from Jilin
            Petrochemical.

      (B)   SALE OF PETROCHEMICAL PRODUCTS

            The price of the petrochemical products sold by the Company to Jilin
            Petrochemical has increased substantially in line with the increase
            in the market price of petrochemical products in the PRC, which
            tracks an increase in the price of crude oil in the international
            market by approximately 47% in the first half of 2005. The price of
            petrochemical products sold by the Company to Jilin Petrochemical
            has increased by an average of approximately 25% in the first half
            of 2005 compared with the same period in the last year. Such
            substantial increase is beyond the Directors' reasonable
            expectation. The Directors expect an increase of approximately 30%,
            40% and 50%, respectively, in the price of such products for each of
            the years ending 31 December 2007 on a year-on-year basis.

            The amount of the petrochemical products sold by the Company to
            Jilin Petrochemical will also increase substantially following the
            commencement of commercial operation of Jilin Petrochemical's
            expanded polyethylene production facilities in October 2005 and that
            of the Expanded Facilities by the end of 2005 and the commencement
            of expansion of phenol acetone production facilities in 2006 and
            glycol production facilities in 2007.

      (C)   PRODUCTION SAFETY INSURANCE FUNDS

            The Company shall contribute to the production safety insurance plan
            of PetroChina at 0.4% of the average cost of fixed assets and
            inventory. The increase in the caps for such funds is proposed
            mainly due to the increase in the cost of inventory of the Company
            which is beyond the reasonable expectation of the Company due to the
            substantial increase in the price of crude oil, production materials
            and petrochemical products.

      (D)   LEASE OF MACHINERY AND EQUIPMENT

            With the unexpected expansion of plants of Jilin Petrochemical, the
            Company will lease additional machinery and equipment from Jilin
            Petrochemical to benefit from the operation effectiveness and
            proficiency which will cause an increase in the amount of the
            services charges payable to Jilin Petrochemical.

      (E)   RAILWAY TRANSPORT AND WATER TREATMENT SERVICES

            The Company will provide additional railway transport and water
            treatment services to Jilin Petrochemical following the commencement
            of commercial operations of Jilin Petrochemical's various expansion
            projects, which would cause an increase in the amount of services
            charges payable by Jilin Petrochemical beyond the Directors'
            reasonable expectation.

      (F)   PUBLIC UTILITIES SERVICES

            As a substantial part of plants of the Company is co-mingled with
            those of Jilin Petrochemical at the same premises, it would be more
            cost effective for the Company and Jilin Petrochemical to acquire
            public utilities services from each other for those plants. The
            Company and Jilin Petrochemical will provide public utilities to
            each other at market price from the second half of 2005 with the
            commencement of commercial operation of renovated facilities of both
            the Company and Jilin Petrochemical. The Directors expect a
            substantial increase in the amount of such services in 2006 and 2007
            following the completion of various expansion projects by both the
            Company and JCGC and in view of the continuing increase in the
            prices of the public utilities due to that in the prices of power
            and energy.

      (G)   ASSETS MANAGEMENT SERVICE

            The Company will provide a management service of ethylene production
            facilities to Jilin Petrochemical under the Assets Management
            Agreement for a management fee from the second half 2005. The basis
            on which such management fee is determined and its annual caps is
            set out under paragraph 3.4.

      (H)   OTHER SUPPORTING SERVICES

            The Company will provide maintenance services to the production
            facilities of Jilin Petrochemical due to the insufficient capacity
            of Jilin Petrochemical. The Company also expects to provide such
            services to Jilin Petrochemical in its triennial overall overhaul
            and maintenance of production facilities in the second half of 2005.
            Such services will be provided at actual cost.

            The Company will provide landscaping services, job training services
            and other welfare and supporting services as required by Jilin
            Petrochemical with its expansion of operation and labor force. Such
            services will be provided at market price.

            The Directors expect an average increase of approximately 50% in
            2006 and 2007 on a year-on-year basis to satisfy the increasing
            requirements of Jilin Petrochemical in the course of expanding both
            of its operations and labor force.

3.3.3 The basis and reasons for revising the annual caps for the Continuing
      Connected Transactions with JCGC are as follows:

      (A)   SALE OF PRODUCTS

            The price of the products sold by the Company to JCGC has increased
            substantially in line with the increase in the market price of
            petrochemical products in the PRC, which tracks an increase in the
            price of crude oil in the international market by approximately 47%
            in the first half of 2005. The price of petrochemical products sold
            by the Company to JCGC has increased by an average of approximately
            25% in the first half of 2005 compared with the same period in the
            last year. Such substantial increase is beyond the Directors'
            reasonable expectation. The Directors expect an increase of
            approximately 30%, 40% and 50%, respectively, in the price of such
            products for each of the years ending 31 December 2007 on a
            year-on-year basis.

            In addition, the Company will sell certain products to JCGC which
            were previously sold to third parties due to the changes in the
            market, resulting in an increase in the amounts of sale of such
            products.

      (B)   EXAMINATION AND MAINTENANCE SERVICES

            In view of JCGC's improved capacity for examination and maintenance
            services and for the sake of cost effectiveness, the Company will
            acquire a substantial amount of additional examination and
            maintenance services from JCGC instead of third parties to carry out
            examination and maintenance of its production facilities, including
            its triennial overall examination and maintenance in the second half
            of 2005.

      (C)   CONSTRUCTION OF FIXED ASSETS

            The Company will acquire additional fixed assets construction
            services from JCGC in the course of its triennial overall
            examination and maintenance in the second half of 2005. Moreover,
            the Company will acquire an additional amount of such services from
            JCGC as it expects to carry out a series of small scale renovation
            and expansion projects in 2006 and 2007.

      (D)   PURCHASE OF PRODUCTION MATERIALS AND SPARE PARTS

            The price of the production materials purchased by the Company from
            JCGC has increased substantially in line with the increase in the
            market price of petrochemical products in the PRC, which tracks an
            increase in the price of crude oil in the international market by
            approximately 47% in the firs half of 2005. The price of production
            materials purchased by the Company from JCGC has increased by an
            average of approximately 40% in the first half of 2005 compared with
            the same period in the last year. Such substantial increase is
            beyond the Director's reasonable expectation. The Directors expect
            an increase of approximately 30%, 40% and 50%, respectively, in the
            price of such production materials for each of the years ending 31
            December 2007 on a year-on-year basis.

            In addition, the Company will continue to purchase certain
            production materials from JCGC which were purchased from independent
            third parties due to the unexpected changes in the market, resulting
            in an substantial increase in the amounts of purchase of such
            production materials.

      (E)   WELFARE AND SUPPORTING SERVICES

            With the expansion of operations by JCGC, the Company will acquire a
            substantial amount of additional public utilities services from
            JCGC's plants to benefit from the convenience of locations and
            achieve cost effectiveness.

      (F)   OPERATING LEASE RENTALS ON LAND AND PROPERTY

            With the expansion of operations by JCGC, the Company will lease
            additional properties from JCGC's facilities to benefit from the
            convenience of locations and achieve cost effectiveness.

3.4   BASIS FOR THE ANNUAL CAPS FOR THE CONTINUING CONNECTED TRANSACTIONS UNDER
      THE ASSETS MANAGEMENT AGREEMENT

      The management fee payable under the Assets Management Agreement is
      determined with reference to the average amount of actual labor costs
      incurred in the production of ethylene for the two years ended 31 December
      2004 and six months ended 30 June 2005, being RMB21 per tonne of ethylene.
      The annual caps for the management fee payable by Jilin Petrochemical to
      the Company for each of the years ending 31 December 2008 are estimated on
      such basis multiplied by the amount of ethylene attributable to the
      Expanded Facilities and a mark-up of 15% on the labor cost each year
      thereafter. The estimated maximum amount of ethylene attributable to the
      Expanded Facilities will be approximately 260,000 tonnes for each of the
      three years following the commencement of commercial operation of the
      Expanded Facilities.

4.    BREACH OF TWO CAPS FOR ONE CONTINUING CONNECTED TRANSACTION

      In the course of preparing the interim report for the six months ended 30
      June 2005, the Directors noted that while the Company is in compliance
      with the cap set out in the Master Products and Services Agreement for the
      total amount of the Continuing Connected Transactions with PetroChina for
      the year ending 31 December 2005, the estimated maximum amount for the
      purchase of production materials by the Company from PetroChina has been
      exceeded. The total amount of production materials purchased by the
      Company from PetroChina for the six months ended 30 June 2005 was
      approximately RMB3,087,316 which exceeds the annual cap for such
      transaction as approved by the independent Shareholders, being
      RMB2,640,000,000.

      Such breach was mainly due to the purchase of a large amount of
      hydrogenated diesel oil by the Company from Jilin Petrochemical in order
      to comply with the new environmental protection standards for diesel oil
      introduced by the PRC government in 2004, which is beyond the Company's
      control and reasonable expectation. To comply with such standards, the
      cracking diesel oil produced by the Company must be refined through the
      hydrogenation treating facility of Jilin Petrochemical and the Company
      will re-purchase the hydrogenated diesel oil for its further processing
      and sales to PetroChina. With the increase in the volume of crude oil, the
      amount of the cracking diesel oil produced by the Company, which must be
      hydrogenated through the hydrogenation treating facilities of Jilin
      Petrochemical, increased accordingly and resulted in a substantial
      increase in the amount of the hydrogenated diesel oil purchased by the
      Company from Jilin Petrochemical.

      The Directors also noted that while the Company is in compliance with the
      cap set out in the Composite Services Agreement for the total amount of
      the Continuing Connected Transactions with JCGC for the year ending 31
      December 2005, the estimated maximum amount for production materials
      purchased by the Company from JCGC has been exceeded. The total amount of
      production materials purchased by the Company from JCGC for the six months
      ended 30 June 2005 was approximately RMB55,903,000 which exceeds the
      annual cap for such transaction as approved by the independent
      Shareholders, being RMB7,480,000.

      Such breach was mainly due to the purchase of a large amount of fatty
      alcohol by the Company from PetroChina which was purchased from a third
      party. As the third party ceased its manufacturing of such production
      material and due to the Company's lack of import license, the Company has
      to import such production material of equivalent standards through a
      subsidiary of JCGC with such license, resulting in a substantial increase
      in the amount of production materials purchased from JCGC.

      The delay in disclosure of and omission in obtaining the independent
      Shareholders' approval for such sale of petrochemical products has
      constituted breaches of the Listing Rules. The Stock Exchange has informed
      the Company that it reserves the rights to take appropriate actions
      against the Company and/or the Directors in respect of the breaches of the
      Listing Rules.

      To remedy such breach, the Directors have resolved to enter into and
      propose for the Shareholders' approval of the Supplemental Agreements to
      revise the annual caps for the Continuing Connected Transactions,
      including but not limited to, the purchase of production materials from
      PetroChina and the purchase of production materials and spare parts from
      JCGC to satisfy the increasing demand for such transactions in the
      ordinary and usual course of the business of the Company. Furthermore, the
      Directors will continue to monitor closely the amount of the Continuing
      Connected Transactions on a monthly basis. The Directors, will
      particularly review the amounts of the Continuing Connected Transactions
      and take prompt actions to make necessary disclosure and obtain
      independent Shareholders' necessary approval as required under the Listing
      Rules if the amount of any of the Continuing Connected Transactions
      exceeds or is likely to exceed the relevant cap.

5.    LISTING RULES IMPLICATIONS FOR SUPPLEMENTAL CONTINUING CONNECTED
      TRANSACTIONS

      PetroChina is the controlling shareholder of the Company and JCGC is a
      wholly-owned subsidiary of the ultimate controlling shareholder of the
      Company. They are respectively Connected Persons of the Company as defined
      under Rule 14A.11 of the Listing Rules. Accordingly, the transactions
      under the Supplemental Agreements and the Assets Management Agreement
      constitute non-exempt continuing connected transactions of the Company
      under Rule 14A.35 of the Listing Rules and are subject to the disclosure
      requirements under Rules 14A.37 to 14A.40, 14A.45 and 14A.47 and the
      approval of the independent Shareholders under Rule 14A.48 of the Listing
      Rules.

6.    APPROVAL BY THE BOARD

      A meeting of the Board was held on 12 August 2005, at which the Board
      approved the entering into of: (i) the Supplemental Master Products and
      Services Agreement with Jilin Petrochemical; (ii) the Supplemental
      Composite Services Agreement with JCGC; and (iii) the Assets Management
      Agreement with Jilin Petrochemical. The votes of Mr. Yu Li, Ms. Yang
      Dongyan, Mr. Ni Muhua, Mr. Jiang Jixiang and Mr. Xiang Ze, who are also
      employees of PetroChina, were not counted. All the remaining six
      Directors, including Mr. Zhang Xingfu, Mr. Li Chongjie, Mr. Wang Peirong,
      Mr. Lu Yanfeng, Mr. Zhou Henlong and Ms. Fanny Li, have approved all such
      agreements.

7.    EXTRAORDINARY GENERAL MEETING AND CLOSURE OF REGISTER OF MEMBERS

      The Board of the Company resolved to convene an Extraordinary General
      Meeting of the Company on 29 September 2005 to approve, among other
      things, the Supplemental Agreements and the Assets Management Agreement.

      PetroChina and its associates will abstain from voting with regard to
      ordinary resolutions in connection with the matters mentioned above to be
      proposed at the Extraordinary General Meeting.

      A circular containing, among other things, details of the Supplemental
      Agreements and the Assets Management Agreement, the recommendations of the
      independent board committee and the advice of Watterson Asia Limited, the
      independent financial adviser of the independent board committee will be
      despatched to the shareholders of the Company.

      The holders of the Company's shares whose names appear on the register of
      members of the Company at 4:00 pm on 30 August 2005 will be entitled to
      attend the Extraordinary General Meeting. The register of members of the
      Company will be closed from 31 August 2005 to 29 September 2005 (both days
      inclusive), during which no transfer of H Shares will be effected.

      THE SUPPLEMENTAL AGREEMENTS AND THE ASSETS MANAGEMENT AGREEMENT MAY OR MAY
      NOT BE APPROVED BY THE INDEPENDENT SHAREHOLDERS. SHAREHOLDERS AND
      POTENTIAL SHAREHOLDERS ARE ADVISED TO EXERCISE CAUTION WHEN DEALING IN THE
      SHARES OF THE COMPANY.
