LETTER FROM THE PRESIDENT 5/31/03
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

[Sidebar]
- --------------------------------------------------------------------------------
Osbert Hood was recently named Chief Executive Officer and President of Pioneer
Investment Management USA Inc., the U.S. investment arm of Pioneer Global Asset
Management. Mr. Hood had been Chief Operating Officer at Pioneer U.S. and a key
member of the senior management committee. He joined Pioneer in 2000, having
previously held senior management positions at both John Hancock Financial
Services and American Express.
- --------------------------------------------------------------------------------

The favorable conclusion of the war with Iraq coupled with guarded optimism on
the economy set off a strong stock market rally after several months of
volatility. Corporate bond prices also rose, as investors sought higher returns.

After the war, domestic factors such as taxes and the outlook for corporate
earnings took center stage. Recent cuts in tax rates on dividends and capital
gains, designed to encourage investment and lower personal income taxes, could
energize the economy. The Federal Reserve Board appears committed to low
interest rates, keeping borrowing costs low for businesses and consumers.
Interest rates have been cut in Europe as well, in the hope of reviving sluggish
economies on the other side of the Atlantic. Meanwhile, the weaker U.S. dollar
is boosting business for American companies that operate in overseas markets.

Independent research remains the key

Pioneer is not in the business of forecasting economic trends or geopolitical
events. Our focus remains, as it has since 1928, on intensive research aimed at
finding the best values for our shareowners. Our managers and analysts spend
every day looking for companies with strong finances and positive prospects;
financially strong companies have greater potential to grow when the economy
eventually rights itself. Pioneer's fixed-income experts are also finding bonds
both here and overseas that offer good current yields and potential for higher
prices.

Consult a trusted advisor

Whenever the news is troubling, it's tempting to change course. But timing the
market - moving in and out as events unfold - can be costly in terms of lost
opportunities; there's no predicting when a rebound might begin. You can temper
that risk by not speculating on market moves and relying instead on
dispassionate professional advice. So invest some time and meet with a trusted
financial advisor who brings the dual advantages of knowledge and experience to
the table.

All of us at Pioneer thank you for your continued business.

PORTFOLIO MANAGEMENT DISCUSSION 5/31/03
- --------------------------------------------------------------------------------

For the six months ended May 31, 2003, Pioneer Emerging Markets Fund's Class A
shares delivered a total return at net asset value of 10.68%. Over the same time
period, the MSCI Emerging Markets Free Index had a total return of 6.03%.

In the following discussion, Mark Madden, portfolio manager of Pioneer Emerging
Markets Fund, addresses the factors impacting the Fund's performance and the
outlook for the emerging markets.

Q:   What factors influenced the performance of emerging markets in the six
     months ended May 31, 2003?

A:   Emerging markets performance has improved in the last few months as the
     prospects for global growth are looking better following the swift
     completion of the war in Iraq. Many expect corporate earnings to strengthen
     due to corporate restructuring efforts and low interest rates, which reduce
     financing costs and help propel consumer spending.

     In the last six months several emerging market countries experienced sharp
     recoveries in their financial markets. Brazil was one of the strongest
     performing markets due in part to proposed economic policies by the new
     president, Luiz Inacio Lula da Silva. The Brazilian market had declined
     last year on fears that the president would implement populist policies
     that would lower economic growth prospects and increase financing costs.
     These fears have proved thus far to be unfounded. Russia also had strong
     performance in the last six months due to high oil prices (Russia is a
     major oil producer), prospects for reform in Russia's electric power
     industry, and due to merger and acquisition activity in the Russian market
     that highlighted the attractive valuations of Russian stocks.

     Pioneer Emerging Markets Fund's total return was higher than its benchmark,
     the MSCI Emerging Markets Free Index, over the last six months. The Fund's
     focus on Brazil and good stock selection in India contributed positively to
     performance. The Fund also benefited from its deemphasis on the technology
     sector, which was the worst performing sector during the last six months
     due to the disappointing earnings and high valuations of stocks in the
     sector.

     The Fund's underweight position in Israel detracted slightly from
     performance. The Israeli market rebounded after Israel escaped negative
     repercussions from the war in Iraq (as many had expected), and the
     prospects for a peaceful settlement of the Israeli/Palestinian conflict
     improved.

Q:   What is your investment strategy?

A:   Our investment process is driven by rigorous research that focuses on
     companies that sell at a discount to our estimation of fair value, with
     strong long-term growth prospects and proven management ability. We look
     for companies that are well positioned in industries with favorable
     long-term trends and growth potential. We manage risk through
     diversification among various countries, sectors and companies while
     emphasizing stocks that are attractively valued.

Q:   Where are you finding attractive opportunities in emerging markets?

A:   We are particularly optimistic about the prospects for India, Thailand and
     Indonesia. In India, we find many attractively valued stocks across a range
     of sectors and are optimistic about the economic growth prospects if the
     Indian government can continue to pursue economic reform measures.
     Thailand's economic growth may continue to accelerate as the financial
     restructuring that has been in progress the last few years begins to reap
     benefits. Indonesia's political situation has been stable, and Indonesian
     stocks are among the cheapest in emerging markets. Indonesian interest
     rates may continue to decline, which would be very positive to the stock
     market.

     As for sectors, we continue to maintain an underweight position in the
     technology sector. We believe earnings are likely to continue to be
     disappointing due to intense pressure on profit margins, and stock
     valuations are still high.


                                                                               9

PORTFOLIO MANAGEMENT DISCUSSION 5/31/03                              (continued)
- --------------------------------------------------------------------------------

Q:   What is your outlook?

A:   We believe emerging markets offer attractive potential due to the low
     relative valuations in emerging markets. Many companies in emerging markets
     are gaining global market share by delivering quality products and services
     at very competitive prices. Due to these trends, we expect earnings and
     cash flow growth to be strong. The primary risk relates to the health of
     the global economy, which has a direct impact on export growth and domestic
     confidence. Still, we believe there is significant value in emerging market
     stocks relative to their own history and relative to their developed market
     peers.


The preceding information is the opinion of Fund management. Past performance is
no guarantee of future results, and there is no guarantee that market forecasts
discussed will be realized.

Investing in emerging markets carries its own set of risks, including but not
limited to, currency fluctuations, and social and economic instability. However,
we feel confident that the long-term prospects invite serious consideration.

NOTES TO FINANCIAL STATEMENTS 5/31/03 (unaudited)
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Emerging Markets Fund (the Fund) is a Delaware business trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek long-term
growth of capital.

The Fund offers five classes of shares - Class A, Class B, Class C, Class R, and
Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of the Fund and has equal rights to voting,
redemptions, dividends and liquidation, except that the level of transfer agent
and distribution fees may differ among classes. Class A, Class B, Class C and
Class R shareowners have exclusive voting rights with respect to the
distribution plan for each class. There is no distribution plan for Class Y
shares.

The Fund's financial statements have been prepared in conformity with accounting
principles generally accepted in the United States of America that require the
management of the Fund to, among other things, make estimates and assumptions
that affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and liabilities at the date of the financial statements, and
the reported amounts of revenues and expenses during the reporting periods.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Fund, which are in
conformity with those generally accepted in the investment company industry:

A.   Security Valuation

Security transactions are recorded as of trade date. The net asset value is
computed once daily, on each day the New York Stock Exchange is open, as of the
close of regular trading on the Exchange. In computing the net asset value,
securities are valued at the last sale price on the principal exchange where
they are traded. Securities that have not traded on the date of valuation, or
securities for which sale prices are not generally reported, are valued at the
mean between the last bid and asked prices. Securities for which market
quotations are not readily available are valued at their fair values as
determined by, or under the direction of, the Board of Trustees. Trading in
foreign securities is substantially completed each day at various times prior to
the close of the New York Stock Exchange. The values of such securities used in
computing the net asset value of the


                                                                              33


Pioneer Emerging Markets Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 5/31/03 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

     Fund's shares are determined as of such times. Dividend income is recorded
     on the ex-dividend date, except that certain dividends from foreign
     securities where the ex-dividend date may have passed are recorded as soon
     as the Fund is informed of the ex-dividend data in the exercise of
     reasonable diligence. Interest income including interest on income bearing
     cash accounts is recorded on the accrual basis. Dividends and interest
     income are recorded net of unrecoverable foreign taxes withheld at the
     applicable country rates. Temporary cash investments are valued at
     amortized cost.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

     The Fund's investments in emerging markets or countries with limited or
     developing markets may subject the Fund to a greater degree of risk than in
     a developed market. Risks associated with these developing markets include
     political, social or economic factors and may affect the price of the
     Fund's investments and income generated by these investments, as well as
     the Fund's ability to repatriate such amounts.

B.   Foreign Currency Translation

     The books and records of the Fund are maintained in U.S. dollars. Amounts
     denominated in foreign currencies are translated into U.S. dollars using
     current exchange rates.

     Net realized gains and losses on foreign currency transactions represent,
     among other things, the net realized gains and losses on foreign currency
     contracts, disposition of foreign currencies and the difference between the
     amount of income accrued and the U.S. dollars actually received. Further,
     the effects of changes in foreign currency exchange rates on investments
     are not segregated in the statement of operations from the effects of
     changes in market price of those securities but are included with the net
     realized and unrealized gain or loss on investments.

C.   Forward Foreign Currency Contracts

     The Fund enters into forward foreign currency contracts (contracts) for the
     purchase or sale of a specific foreign currency at a fixed price on a
     future date as a hedge or cross-hedge against either specific


34


Pioneer Emerging Markets Fund

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

     investment transactions (settlement hedges) or portfolio positions
     (portfolio hedges). All contracts are marked to market daily at the
     applicable exchange rates, and any resulting unrealized gains or losses are
     recorded in the Fund's financial statements. The Fund records realized
     gains and losses at the time a portfolio hedge is offset by entry into a
     closing transaction or extinguished by delivery of the currency. Risks may
     arise upon entering into these contracts from the potential inability of
     counterparties to meet the terms of the contract and from unanticipated
     movements in the value of foreign currencies relative to the U.S. dollar
     (see Note 6).

D.   Futures Contracts

     The Fund may enter into futures transactions to hedge against changes in
     interest rates, securities prices, and currency rates or to seek to
     increase total return. Upon entering into a futures contract, the Fund is
     required to deposit with a broker an amount of cash or securities equal to
     the minimum "initial margin" requirements of the associated futures
     exchange. Subsequent payments for futures contracts ("variation margin")
     are paid or received by the Fund, depending on the daily fluctuation in the
     value of the contracts, and are recorded by the Fund as unrealized gains or
     losses. When the contract is closed, the Fund realizes a gain or loss equal
     to the difference between the opening and closing values of the contract.
     The use of futures contracts involves, to varying degrees, elements of
     market risks which may exceed the amounts recognized by the Fund. Changes
     in value of the contracts may not directly correlate to the changes in
     value of the underlying securities. These risks may decrease the
     effectiveness of the Fund's hedging strategies and potentially result in a
     loss. At May 31, 2003, the Fund had no open futures contracts.

E.   Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     In addition to the requirements of the Internal Revenue Code, the Fund may
     also be required to pay local taxes on the recognition of


                                                                              35


Pioneer Emerging Markets Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 5/31/03 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

     capital gains and/or the repatriation of foreign currencies in certain
     countries. During the six months ended May 31, 2003, the Fund paid no such
     taxes.

     In determining the daily net asset value, the Fund estimates the reserve
     for such taxes, if any, associated with investments in certain countries.
     Any estimated reserve for the capital gains is based on the net unrealized
     appreciation on certain portfolio securities, the holding period of such
     securities and the related tax rates, tax loss carryforward (if applicable)
     and other such factors. As of May 31, 2003, the Fund had no reserve related
     to capital gains. Any estimated reserve for the repatriation of foreign
     currencies is based on principal balances and/or unrealized appreciation of
     applicable securities, the holding period of such investments and the
     related tax rates and other such factors. As of May 31, 2003, the fund had
     no reserve related to taxes on the repatriation of foreign currencies.

     The characterization of distributions to shareowners for financial
     reporting purposes is determined in accordance with federal income tax
     rules. Therefore, the source of the Fund's distributions may be shown in
     the accompanying financial statements as either from or in excess of net
     investment income or net realized gain on investment transactions, or from
     paid-in capital, depending on the type of book/tax differences that may
     exist.

F.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.
     (UniCredito Italiano), earned $6,274 in underwriting commissions on the
     sale of Fund shares during the six months ended May 31, 2003.

G.   Class Allocations

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B, Class C, and Class R shares of the Fund,
     respectively. Class Y shares are not subject to a distribution plan.
     Shareowners of each class share all expenses and fees paid to the transfer
     agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS),
     for its services, which are allocated based on the number of accounts in
     each class and


36


Pioneer Emerging Markets Fund

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

     the ratable allocation of related out-of-pocket expenses (see Note 3).
     Income, common expenses and realized and unrealized gains and losses are
     calculated at the Fund level and allocated daily to each class of shares
     based on their respective percentage of adjusted net assets at the
     beginning of the day.

     Distributions to shareowners are recorded as of the ex-dividend date.
     Distributions paid by the Fund with respect to each class of shares are
     calculated in the same manner, at the same time, and in the same amount,
     except that Class A, Class B, Class C, Class R and Class Y shares can bear
     different transfer agent and distribution fees.

H.   Securities Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors, with the Fund's custodian acting as the
     lending agent. When entering into a loan, the Fund receives collateral,
     which is maintained by the custodian and earns income in the form of
     negotiated lenders' fees. The Fund also continues to receive interest or
     dividends on the securities loaned and gain or loss in the value of the
     loaned securities that may occur during the term of the loan will be for
     account of the Fund. The loans are secured by collateral of at least 102%,
     at all times, of the fair value of the securities loaned. The fair value of
     the collateral is adjusted daily to reflect any price fluctuation in the
     value of the loaned securities. The value of loaned securities and cash
     collateral at period end are disclosed on the balance sheet. The Fund
     invests cash collateral in the Securities Lending Investment Fund, which is
     managed by Brown Brothers Harriman & Co., the Fund's custodian.

I.   Repurchase Agreements

     With respect to repurchase agreements entered into by the Fund, the value
     of the underlying securities (collateral), including accrued interest
     received from counterparties, is required to be at least equal to or in
     excess of the value of the repurchase agreement at time of purchase. The
     collateral for all repurchase agreements is held in safekeeping in the
     customer-only account of the Fund's custodian, or subcustodians. The Fund's
     investment adviser, Pioneer Investment Management, Inc. (PIM), is
     responsible for determining that the value of the collateral remains at
     least equal to the repurchase price.


                                                                              37

2. Management Agreement

UniCredito Italiano. Management fees are calculated daily at the annual rate of
1.25% of the Fund's average daily net assets.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At May 31, 2003, $210,332, was payable to PIM
related to management fees, administrative fees and certain other services.

3. Transfer Agent

4. Distribution and Service Plans

The Fund adopted a Plan of Distribution with respect to Class A, Class B, Class
C, and Class R shares (Class A Plan, Class B Plan, Class C Plan, and Class R
Plan) in accordance with Rule 12b-1 under the Investment Company Act of 1940.
Pursuant to the Class A Plan, the Fund pays PFD a service fee of up to 0.25% of
the Fund's average daily net assets in reimbursement of its actual expenditures
to finance activities primarily intended to result in the sale of Class A
shares. Pursuant to the Class B Plan and the Class C Plan, the Fund pays PFD
1.00% of the average daily net assets attributable to each class of shares. The
fee consists of a 0.25% service fee and a 0.75% distribution fee paid as
compensation for personal services and/or account maintenance services or
distribution services with regard to Class B and Class C shares. Pursuant to the
Class R Plan, the Fund pays PFD 0.50% of the average daily net assets
attributable to Class R shares for distribution services. Included in due to
affiliates is $60,539 in distribution fees payable to PFD at May 31, 2003. The
Fund also has adopted a separate service plan for Class R shares (Service Plan).
The Service Plan authorizes the Fund to pay securities dealers, plan
administrators or other service organizations that agree to provide certain
services to retirement plans or plan participants holding shares of the Fund a
service fee of up to 0.25% of the Fund's average daily net assets attributable
to Class R shares held by such plans.

- --------------------------------------------------------------------------------

In addition, redemptions of each class of shares (except Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within one year of purchase. Class B shares that are redeemed within six years
of purchase are subject to a CDSC at declining rates beginning at 4.00%, based
on the lower of cost or market value of shares being redeemed. Redemptions of
Class C shares within one year of purchase are subject to a CDSC of 1.00%.
Redemptions of Class R shares within 18 months of purchase may be subject to a
CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the six months ended
May 31, 2003, CDSCs in the amount of $32,807 were paid to PFD.

5. Expense Offsets

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the six months ended May 31, 2003,
the Fund's expenses were reduced by $4,234 under such arrangements.

6. Forward Foreign Currency Contracts

At May 31, 2003, The Fund may enter into contracts that obligate the Fund to
deliver currencies at specified future dates. At the maturity of a contract, the
Fund must make delivery of the foreign currency. Alternatively, prior to the
settlement date of a portfolio hedge, the Fund may close out such contracts by
entering into an offsetting hedge contract. As of May 31, 2003, the Fund had no
outstanding portfolio or settlement hedges.

7. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), collectively participate in a $50 million committed, unsecured revolving
line of credit facility. Borrowings are used solely for temporary or emergency
purposes. The Fund may borrow up to the lesser of $50 million or the limits set
by its prospectus for borrowings. Interest on collective borrowings is payable
at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an
annual commitment fee for this facility. The commitment fee is allocated among
such Funds based on their respective borrowing limits. For the six months ended
May 31, 2003, there was no borrowing under such agreement.


                                                                              39

of $5,000 or more.)
