Exhibit M-4

          [Cleary, Gottlieb, Steen & Hamilton London Office Letterhead]




                                                               November 13, 2002



To: The Korea Development Bank

16-3, Yoido-dong

Youngdungpo-gu

Seoul, Korea



Ladies and Gentlemen:

     We have acted as English counsel to The Korea Development Bank (the
"Issuer"), a statutory juridical entity established in the Republic of Korea
under The Korea Development Bank Act of 1953, in connection with the preparation
and filing with the U.S. Securities and Exchange Commission (the "Commission")
under the U.S. Securities Act of 1933 (the "Securities Act") of the Issuer's
registration statement under Schedule B (No. 333-97299) (the "Registration
Statement") relating to the offering from time to time, as set forth in the
Registration Statement, the form of prospectus contained therein (the
"Prospectus") and one or more supplements to the Prospectus, of the Issuer's
unsecured debt securities (the "Debt Securities") and guarantees (the
"Guarantees"). The Registration Statement relates to Debt Securities and
Guarantees having an aggregate initial public offering price or purchase price
of up to approximately U.S.$6,621,000,000 or the equivalent thereof. Certain of
the Guarantees are to be issued in the form of deed poll guarantees (the "Deed
Poll Guarantees") or securities guarantees pursuant to a guarantee agreement
dated November 13, 2002 between the Issuer and Korea Electric Power Corporation.

     In arriving at the opinions expressed below we have reviewed the specimen
form of the Deed Poll Guarantees attached to this letter.

     In rendering the opinions expressed below we have assumed and not verified:

                                       1



     (a) that each Deed Poll Guarantee will be or has been executed in the
         specimen attached to this letter;

     (b) that each Deed Poll Guarantee has been or will be duly authorised by
         the Issuer and that the Issuer has the power, capacity and authority to
         execute and deliver and to perform its obligations contained in such
         Deed Poll Guarantee;

     (c) the accuracy as to factual matters of each Deed Poll Guarantee
         (including, without limitation, the accuracy of the representations and
         warranties of the Issuer) and the compliance by the Issuer with its
         obligations under each Deed Poll Guarantee.

     Based on the foregoing, and subject to the further qualifications and
limitations set forth below, it is our opinion that each Deed Poll Guarantee,
when duly executed and delivered by the Issuer, will constitute a valid, binding
and enforceable obligation of the Issuer.

     The expression "enforceable" as used above means that the obligations
referred to are of the type which English courts enforce. It does not mean that
those obligations will necessarily be enforced in all circumstances in
accordance with their terms. In particular, but without limitation:

     (a) The opinion set forth above as regards the binding effect and validity
         of the obligations and their enforceability against the contracting
         parties is subject to all limitations resulting from the laws of
         bankruptcy, insolvency, liquidation, administration, reorganisation,
         suretyship or similar laws of general application affecting creditors'
         rights.

     (b) Enforcement may be limited by general principles of equity. For
         example, equitable remedies may not be available where damages are
         considered to be an adequate remedy.

     (c) Where any obligations of any person are to be performed or observed in
         jurisdictions outside England, or by a person subject to the laws of a
         jurisdiction outside England, such obligations may not be enforceable
         under English law to the extent that performance or observance thereof
         would be illegal or contrary to public policy under the laws of any
         such jurisdiction.

     (d) The choice of English law as the governing law of the Deed Poll
         Guarantees may be limited by the Contracts (Applicable Law) Act 1991 in
         certain circumstances, including, for example, in respect of laws which
         cannot be derogated from by contract or which are, irrespective of the
         governing law of the contract, mandatory in the relevant forum.

     (e) Where any person is vested with a discretion, or may determine any
         matter in its opinion, English law may require that such discretion is
         exercised reasonably or that such opinion is based on reasonable
         grounds.

     (f) Enforcement of rights may be or become limited by prescription or by
         the lapse of time or may be or become subject to defences of set-off or
         counterclaim.


                                       2



     (g) An English court is able, where the amount of a claim is denominated in
         a currency other than sterling, to give judgment in that other
         currency, as a matter of current procedural practice and at its own
         discretion.

     (h) Except in those cases where jurisdiction is determined in accordance
         with the provisions of the Council Regulation (EC) 44/2001 on
         jurisdiction and the recognition and enforcement of judgements in civil
         and commercial matters, the Brussels Convention on Jurisdiction in
         Civil and Commercial Matters of 1968 or the Lugano Convention on
         Jurisdiction in Civil and Commercial Matters, an English court has
         power to stay an action where it is shown that it can, without
         injustice to the plaintiff, be tried in a more convenient forum.

     (i) Any provision providing that any calculation, certification,
         determination, notification, minute or opinion will be conclusive and
         binding will not be effective if such calculation, certification,
         determination, notification, minute or opinion is fraudulent or made on
         an unreasonable or arbitrary basis or in the event of manifest error
         despite any provision to the contrary and it will not necessarily
         prevent judicial enquiry into the merits of any claim by any party
         thereto.

     (j) Any provision providing for the payment of liquidated damages,
         compensation, additional interest or similar amounts might be held to
         be unenforceable on the ground that it is a penalty.

     (k) Any undertaking or indemnity may be void insofar as it relates to stamp
         duty payable in the United Kingdom.

     (l) An English court may refuse to give effect to any provision of an
         agreement which amounts to an indemnity in respect of the costs of
         enforcement or of unsuccessful litigation brought before an English
         court or where the court has itself made an order for costs.

     (m) Any question as to whether or not any provision of any agreement or
         instrument which is illegal, invalid, not binding, unenforceable or
         void may be severed from the other provisions thereof in order to save
         those other provisions would be determined by an English court in its
         discretion.

     (n) There is some possibility that an English court would hold that a
         judgment on a particular agreement or instrument, whether given in an
         English court or elsewhere, would supersede such agreement or
         instrument to all intents and purposes, so that any obligation
         thereunder which by its terms would survive such judgment might not be
         held to do so.

     (o) In the case of agreements which are not required by law to be in
         writing or evidenced in writing any provision of an agreement under
         hand may be amended by oral agreement or waived between the parties or
         by the conduct of the parties, notwithstanding any provision to the
         contrary. The most common example of a financing agreement which is
         required to be evidenced in writing is a guarantee.


                                       3



     (p) The effectiveness of terms exculpating a party from a liability or duty
         otherwise owed is limited by law.

     (q) The Deed Poll Guarantees may not be enforceable to the extent that the
         English law doctrines of frustration or mistake apply to them.

     (r) A power of attorney may be revoked in certain circumstances, even if it
         is stated to be irrevocable, unless the power of attorney is expressed
         to be irrevocable and is given to secure a proprietary interest of the
         donee of the power or the performance of an obligation owed to the
         donee.

     We express no opinion as to any agreement, instrument, or other document
other than the Deed Poll Guarantees, or as to any liability to tax which may
arise or be incurred as a result of or in connection with any Deed Poll
Guarantee.

     The opinions set out in this opinion letter are limited to the laws of
England as currently applied by the courts in England, and is given on the basis
that this opinion letter will be governed by and construed in accordance with
English law.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement, to the incorporation by reference of this opinion in any
registration statement relating thereto filed by the Issuer with the Commission
pursuant to Rule 462(b) under the Securities Act and to the references to us
under the heading "Legal Matters" in the Prospectus and any prospectus relating
to any such other registration statement, without thereby admitting that we are
"experts" under the Securities Act or the rules and regulations of the
Commission thereunder for purposes of any part of the Registration Statement or
any such other registration statement, including the exhibit as which this
opinion is filed.

                                     Very truly yours,
                                     CLEARY, GOTTLIEB, STEEN & HAMILTON


                                     By    /s/ Andrew Shutter

                           FORM OF DEED POLL GUARANTEE

THIS GUARANTEE is made by way of DEED POLL on o 2003 by THE KOREA DEVELOPMENT
BANK (the "Guarantor"), a statutory juridical entity established under The Korea
Development Bank Act of 1954, as amended, in the Republic of Korea, and wholly
owned by the government of the Republic of Korea, in favour of the holders of
the Notes from time to time (the "Noteholders").

WHEREAS:

(A)      Pursuant to a fiscal agency agreement dated [insert applicable date],
         as amended, supplemented or restated as at the date hereof, between
         Korea Electric Power Corporation, a statutory juridical corporation
         established under The Korea Electric Power Corporation Act of 1980, as
         amended, in the Republic of Korea (the "Issuer" or "KEPCO") and [name
         of Fiscal Agent ] (the "Fiscal Agent") and the other agent named
         therein (the "Fiscal Agency Agreement"), the Issuer has issued [name of
         applicable Eurobond security] (the "Notes"). A reference to a numbered
         condition in this Guarantee shall be a reference to the conditions of
         the Notes (the "Conditions").

(B)      At a meeting of the Noteholders, the Noteholders passed an
         Extraordinary Resolution, inter alia, sanctioning and approving certain
         modifications to the terms and conditions of the Notes (the "Proposed
         Amendments") and a proposal to eliminate the joint and several
         liability with respect to the Notes arising under the Korean Commercial
         Code of KEPCO's generation company subsidiaries (the "Proposal"), as
         set out in the Notice of Meeting dated [insert applicable date]. In
         connection with such Proposed Amendments and the Proposal, the
         Guarantor has agreed, subject to the satisfaction of certain conditions
         precedent, for the benefit of all the Noteholders, on the terms set
         forth herein, to fully, unconditionally and irrevocably guarantee, on
         an unsecured and unsubordinated basis, KEPCO's payment obligations
         under the Notes.

(C)      The aforementioned conditions precedent have been satisfied in respect
         of the Notes;

(D)      The Notes are represented by a permanent global note (the "Global

         the Euroclear System (each a "Clearing System"). The Notes represented
         by the Global Note are credited to a securities account or securities
         accounts with the Clearing Systems. Any Accountholder (as defined in
         the Fiscal Agency Agreement) with the relevant Clearing System which
         has any of the Notes credited to its securities account from time to
         time will, subject to and in accordance with the terms and conditions
         and operating procedures or management regulations of the relevant
         Clearing System, be entitled to transfer such Notes and (subject to and
         upon payment being made by the Issuer to the bearer in accordance with
         the terms of the Global Note) will be entitled to receive payments from
         the relevant Clearing System calculated by reference to the Notes
         credited to its securities account; and

(F)      Capitalised terms not defined herein shall bear the meanings ascribed
         to them in the Fiscal Agency Agreement.

                                       1



NOW THIS GUARANTEE WITNESSES AS FOLLOWS:

1.    The Guarantor as primary obligor fully, unconditionally and irrevocably:

      (a)   guarantees on an unsecured (subject to the provisions of clause 3
            below) and unsubordinated basis to the Noteholders by way of
            continuing guarantee, the due and punctual payment of the principal
            of, premium, if any, and interest thereon and all other amounts
            payable by the Issuer on or in respect of the Notes (including any
            additional amounts which may become payable under Condition [insert
            applicable condition number] (Taxation) of the Notes) and all
            amounts under the Fiscal Agency Agreement as and when the same shall
            become due and payable in accordance with the terms of the Fiscal
            Agency Agreement and the Notes;

      (b)   agrees that, if and each time that the Issuer shall fail to make any
            payments as and when the same shall become due and payable, the
            Guarantor will on demand (without requiring the relevant Noteholder
            first to take steps against the Issuer or any other person) pay to
            the Noteholder such amounts (as to which the certificate of the
            relevant Noteholder shall in the absence of manifest error be final
            and conclusive) in the currency in which the amounts are payable by
            the Issuer (as if the same were paid by the Issuer).

2.    All payments of principal and interest in respect of the Notes that are
      paid or otherwise satisfied by the Guarantor pursuant to this Guarantee
      will be made without deduction or withholding for or on account of any
      present or future taxes, duties, assessments or governmental charges of
      whatever nature imposed or levied by or on behalf of the Republic of Korea
      or any political subdivision or any authority thereof or therein having
      power to tax, unless the deduction or withholding of such taxes, duties,
      assessments or governmental charges is required by law. If the Guarantor
      is required by law to make any such deduction or withholding, the
      Guarantor will pay such additional amounts by way of principal or interest
      as will result in the receipt by the Noteholders or Couponholders of the
      amounts which would otherwise have been receivable in respect of principal
      and interest had no such deduction or withholding been made, except that
      no such additional amounts shall be payable in respect of any Note or
      Coupon presented for payment:

      (a)   by or on behalf of a holder who is subject to such taxes, duties,
            assessments or governmental charges in respect of such Note or
            Coupon by reason of his being connected with the Republic of Korea
            otherwise than merely by holding such Note or Coupon or receiving
            principal or interest in respect thereof;

      (b)   by or on behalf of a holder who would not be liable for or subject
            to such deduction or withholding by making a declaration of
            non-residence or other similar claim for exemption to the relevant
            tax authority if, after having been requested to make such a
            declaration or claim, such holder fails to do so; or

      (c)   more than thirty days after the Relevant Date (as defined below)
            except to the extent that the holder thereof would have been
            entitled to such additional payment on presenting the same for
            payment on the last day of such thirty-day period.

      For the purposes of this clause 2:

                                       2



      (x)   the "Relevant Date" in relation to any Note or Coupon means the date
            on which such payment first becomes due, except that if the amount
            of the moneys payable has not been received in [insert applicable
            time zone] by the Fiscal Agent on or prior to such due date it means
            that date on which, the full amount of such moneys having been so
            received, notice to that effect shall have been duly given to the
            Noteholders or Couponholders in accordance with Condition [insert
            applicable condition number]of the Notes (Notices); and

      (y)   references to principal or interest in respect of the Notes shall be
            deemed also to refer to any additional amounts which may be payable
            under this clause 2.

3.    For so long as this Guarantee remains in effect, the Guarantor will not
      create or permit to subsist any mortgage, charge, pledge or other security
      interest upon the whole or any part of its assets, present or future, to
      secure any indebtedness, or to secure any guarantee of indebtedness,
      unless the Guarantee shall be secured equally and ratably therewith,
      except that the Guarantor may create or permit to arise or subsist:

      (a)   any encumbrance over promissory notes or other commercial paper
            discounted or otherwise provided as security to or issued by the
            Guarantor where such encumbrance is created in favour of The Bank of
            Korea in the normal operation of its discount facilities or its
            facilities for the funding of loans by the Guarantor to customers of
            the Guarantor; or

      (b)   any encumbrance over any immovable property owned by the Guarantor
            as security for the repayment by the Guarantor to a tenant of that
            property of any key money paid by such tenant to the Guarantor upon
            taking a tenancy or lease of that property; or

      (c)   any statutory lien arising in the ordinary course of the Guarantor's
            business and not in connection with the borrowing or raising of
            money; or

      (d)   any encumbrance arising or preference given under Korean law,
            applicable generally to corporations established under Korean law,
            by virtue of a failure by the Guarantor to meet an obligation,
            provided that such encumbrance shall not be permitted to subsist for
            more than 30 days; or

      (e)   any encumbrance over any asset purchased by the Guarantor (or
            documents of title thereto) or arising in connection with
            improvements to any asset of the Guarantor as security for the
            unpaid balance of the purchase price thereof or costs of improvement
            thereto.

4.    The obligations of the Guarantor under this Guarantee shall not be
      affected by any matter or thing which but for this provision might operate
      to affect the Guarantor's obligations, including, without limitation:

      (a)   any time or indulgence granted to or composition with the Issuer or
            any other person;

      (b)   the taking, variation, renewal or release of remedies or securities
            against the Issuer or any other person;


                                       3




      (c)   any unenforceability, invalidity or irregularity of the Notes, the
            Fiscal Agency Agreement or the Guarantee Agreement entered into
            between the Guarantor and KEPCO dated November 13, 2002 (the
            "Guarantee Agreement"); or

      (d)   any term or other provision of the Guarantee Agreement.

5.    Where any discharge (whether in respect of the obligations of the Issuer
      or any security for the obligations of the Issuer or otherwise) is made in
      whole or in part or any arrangement is made on the faith of any payment,
      security or other disposition which is avoided or must be repaid on
      bankruptcy, liquidation or otherwise without limitation, the liability of
      the Guarantor under this Guarantee shall continue as if there had been no
      discharge or arrangement except by payment in full of the principal,
      premium, if any, and interest thereon and all other amounts payable on or
      in respect of the Notes and the Fiscal Agency Agreement. The Guarantor
      covenants that this Guarantee will not be discharged with respect to any
      Note except by payment in full of the principal thereof, interest and any
      other amounts due thereon. The Guarantor waives notice of any default
      under the Fiscal Agency Agreement or the Notes. Notwithstanding anything
      in this Guarantee, the Fiscal Agency Agreement or the Guarantee Agreement,
      the Guarantor hereby agrees that its obligations hereunder shall not be
      affected by any defence, right of set-off or similar right (with respect
      to KEPCO or any other person), counterclaim, recoupment or termination.
      Each Noteholder, acting bona fide and in good faith, shall be entitled to
      concede or compromise any claim that any payment, security or other
      disposition is liable to avoidance or repayment.

6.    The Guarantor represents, warrants and covenants with each Noteholder
      that:

      (a)   it is a statutory banking institution duly organised under the laws
            of the Republic of Korea and has and will have the necessary power
            to enable it to execute, deliver and perform its obligations under
            this Guarantee;

      (b)   subject to the provisions of clause 3 hereof, this Guarantee
            constitutes a full unconditional and irrevocable, on an unsecured
            and unsubordinated basis, obligation of the Guarantor and will rank
            pari passu with all other outstanding and future unsecured and
            unsubordinated obligations of the Guarantor (subject to certain
            statutory exceptions under the laws of the Republic of Korea);

      (c)   this Guarantee constitutes its legal, valid and binding obligations,
            enforceable against it;

      (d)   all necessary consents and authorisations (if any) to enable it to
            enter into this Guarantee have been obtained and are and will remain
            in full force and effect;

      (e)   the execution, delivery and performance of this Guarantee will not
            conflict with (i) any agreement binding on it or any of its assets;
            (ii) its constitutive documents, or (iii) any applicable law; and

      (f)   that, for the avoidance of doubt, this Guarantee constitutes a
            guarantee of payment (and not a guarantee of collection) and waives
            any right to require that any resort be had by any holder or the
            Fiscal Agent or the Paying Agent under the Fiscal Agency Agreement
            to any security held for payment of the obligations guaranteed
            thereunder.


                                       4





7.    The Guarantor shall be subrogated to all rights of the Noteholders against
      the Issuer in respect of any amounts paid to the Noteholders by the
      Guarantor pursuant to this Guarantee, provided, however, that the
      Guarantor shall not be entitled to enforce or to receive any payments
      arising out of or based upon its rights of subrogation if, at the time of
      any such payments, any amounts are due and unpaid by the Guarantor under
      this Guarantee.

8.    The obligations of the Guarantor hereunder shall not be affected by (i)
      the failure of any Noteholder or the Fiscal Agent or Paying Agent to
      assert any claim or demand or to enforce any right to remedy against the
      Issuer or any other person under the Fiscal Agency Agreement, the Notes or
      any other agreement or otherwise; (ii) any rescission, waiver, amendment
      or modification of any of the terms or provisions of the Fiscal Agency
      Agreement, the Notes or any other agreement, (iii) the release of any

            terms of this Guarantee shall remain in full force and effect only
            as to the amounts agreed to be guaranteed hereunder and on the same
            terms as if no such amendment or modification as aforementioned had
            occurred.

15.   This Guarantee is governed by, and shall be construed in accordance with,
      the laws of England.

16.   The Guarantor hereby irrevocably agrees, for the exclusive benefit of the
      Noteholders and the Accountholders, that the courts of England are to have
      non-exclusive jurisdiction to settle any disputes which may arise out of
      or in connection with this Guarantee and that accordingly any suit, action
      or proceedings (together referred to as "Proceedings") arising out of or
      in connection with this Guarantee may be brought in such courts.

17.   The Guarantor hereby irrevocably waives any objection which it may have
      now or hereafter to the laying of the venue of any such Proceedings in any
      such court and any claim that any such Proceedings have been brought in an
      inconvenient forum and hereby further irrevocably agrees that a judgment
      in any such Proceedings brought in the English courts shall be conclusive
      and binding upon it and may be enforced in the courts of any other
      jurisdiction. Nothing contained in this clause shall limit any right to
      take Proceedings against the Guarantor in any other court of competent
      jurisdiction, nor shall the taking of Proceedings in one or more
      jurisdictions preclude the taking of Proceedings in any other
      jurisdiction, whether concurrently or not.

      may be served on it by being delivered to The Korea Development Bank,
      London branch at its principal place of business for the time being in

      Guarantor ceases to maintain a branch in England, the Guarantor shall
      appoint a further person in England to accept service of process on its
      behalf.

19.   Nothing herein shall affect the right to serve process in any manner
      permitted by law.
