Seoul, Korea


Ladies and Gentlemen:


     We have acted as special United States counsel to The Korea Development
Bank, a statutory juridical entity established in the Republic of Korea under
The Korea Development Bank Act of 1953, as amended (the "Bank"), in connection
with the Bank's offering pursuant to a registration statement under Schedule B
(No. 333-111608) of $550,000,000 aggregate principal amount of its floating rate
notes due 2009 (the "Notes") to be issued under a fiscal agency agreement dated
as of February 15, 1991, as amended by Amendment No. 1 thereto dated as of June
25, 2004 (the "Fiscal Agency Agreement"), between the Bank and The Bank of New
York, as fiscal agent (the "Fiscal Agent"). Such registration statement, as
amended when it became effective, is herein called the "Registration Statement;"
the related prospectus dated September 30, 2004, as first filed with the
Securities and Exchange Commission (the "Commission") pursuant to Rule 424(b)(2)
under the Securities Act of 1933, as amended (the "Securities Act"), is herein
called the "Base Prospectus;" the prospectus supplement dated October 13, 2004,
as first filed with the Commission pursuant to Rule 424(b)(2) under the
Securities Act, is herein called the "Prospectus Supplement;" and the Base
Prospectus and the Prospectus Supplement, together, are herein called the
"Prospectus."


     In arriving at the opinion expressed below, we have reviewed the following
documents:

     (a)  the Registration Statement;

     (b)  the Prospectus;

     (c)  a facsimile copy of the Notes in global form as executed by the Bank
          and authenticated by the Fiscal Agent; and

     (d)  an executed copy of the Fiscal Agency Agreement.

In addition, we have reviewed the originals or copies certified or otherwise
identified to our satisfaction of all such records of the Bank and such other
instruments and other certificates of public officials, officers and
representatives of the Bank and such other persons, and we have made such
investigations of law, as we have deemed appropriate as a basis for the opinion
expressed below.


                                     II-15


     In rendering the opinion expressed below, we have assumed the authenticity
of all documents submitted to us as originals and the conformity to the
originals of all documents submitted to us as copies. In addition, we have
assumed and have not verified the accuracy as to factual matters of each
document we have reviewed.

     Based on the foregoing, and subject to the further assumptions and
qualifications set forth below, it is our opinion that the Notes are the valid,
binding and enforceable obligations of the Bank, entitled to the benefit of the
Fiscal Agency Agreement.

     In connection with the foregoing opinion, we note that: (a) we have assumed
that each of the Bank and the Fiscal Agent has satisfied those legal
requirements that are applicable to it to the extent necessary to make the
Fiscal Agency Agreement and the Notes enforceable against it (except that no
such assumption is made as to the Bank regarding matters of the federal law of
the United States of America or the law of the State of New York that in our
experience normally would be applicable with respect to the Fiscal Agency
Agreement and the Notes), (b) such opinion is subject to applicable bankruptcy,
insolvency and similar laws affecting creditors' rights generally and to general
principles of equity, (c) such opinion is subject to the effect of judicial
application of foreign laws or foreign governmental actions affecting creditors'
rights, (d) the enforceability of the waiver of immunities by the Bank set forth
in the Notes is subject to the limitations imposed by the Foreign Sovereign
Immunities Act of 1976 and (e) we express no opinion as to the subject matter
jurisdiction of any United States federal court to adjudicate any action
relating to the Notes where jurisdiction based on diversity of citizenship under
28 U.S.C. Section 1332 does not exist.

     The foregoing opinion is limited to the federal law of the United States of
America and the law of the State of New York.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Legal
Matters" in the Prospectus, 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, including the
exhibit as which this opinion is filed.


                                        Very truly yours,

           Re:   The Korea Development Bank: Offering of US$550,000,000 Floating
                 Rate Notes due 2009

Dear Sirs,

     We have acted as Korean legal counsel for The Korea Development Bank
("KDB"), a governmental financial institution established pursuant to The Korea
Development Bank Act of 1953, as amended, in the Republic of Korea ("Korea") in
connection with KDB's offering pursuant to a registration statement under
Schedule B (No. 333-111608) (as amended when it became effective, the
"Registration Statement") of US$550,000,000 aggregate principal amount of KDB's
floating rate notes due 2009 (the "Notes") to be issued under a fiscal agency
agreement dated as of February 15, 1991, as amended as of June 25, 2004, (the
"Fiscal Agency Agreement") between KDB and The Bank of New York, as fiscal agent
(the "Fiscal Agent").

     For the purposes of giving the legal opinions set forth herein, we have
examined all such laws and regulations of Korea as are relevant, and originals
or copies, certified or otherwise identified to our satisfaction, of the
documents, records, certificates of public officials and other instruments as we
have deemed necessary or advisable. In conducting such examination, we have
assumed the genuineness of all signatures and the authenticity of all documents
submitted to us as originals and the conformity with the originals of all
documents submitted to us as copies thereof, the power and authority of all
parties other than KDB to enter into, and due execution and delivery by such
parties of the documents referred to above. We have also assumed that such
documents constitute the legal, valid and binding obligations of each of the
parties thereto and there has been no breach of any of the terms thereof.

     In addition, and without prejudice to the generality of the immediately
preceding paragraph, in arriving at the opinion expressed below, we have
reviewed the following specific documents relating to the Notes:

     (a)  the Registration Statement;

     (b)  the related prospectus dated September 30, 2004, as supplemented by
          the prospectus supplement dated October 13, 2004 and as first filed
          with the


                                     II-18



          Securities and Exchange Commission pursuant to Rule 424(b)(2) under
          the Securities act of 1933, as amended (the "Prospectus");

     (c)  a facsimile copy of the Notes in global form as executed by KDB and
          authenticated by the Fiscal Agent; and

     (d)  an executed copy of the Fiscal Agency Agreement.

     As to any other matters of fact material to the opinion expressed herein,
we have made no independent inquiry and have relied solely upon the certificates
or oral or written statements of officers and other representatives of KDB.

     We are admitted to practice law in Korea, and the legal opinions provided
herein are confined to and given on the basis of the laws of Korea in effect as
at the date hereof. We do not represent ourselves to be familiar with the laws
of any jurisdiction other than Korea, and we do not pass upon nor express any
opinion in respect of those matters that are governed by or construed in
accordance with any of such laws.

     Based on the foregoing and subject to the reservations and qualifications
set out below, we are of the opinion that:

(1)  KDB is a statutory juridical entity duly established under the Korea
     Development Bank Act of 1953, as amended, and validly existing under the
     laws of Korea, with power and authority to own its properties and conduct
     its business as described in the Prospectus forming a part of the
     Registration Statement;

(2)  The Fiscal Agency Agreement has been duly authorized and executed by KDB;

(3)  The statements in the Prospectus concerning matters of Korean law are
     accurate and up-to-date as of the date hereof; and

(4)  The Notes have been duly authorized, executed, issued and delivered by KDB
     and constitute valid, binding and enforceable obligations of KDB.

     We express no opinion as to any agreement, instrument or other documents
other than as specified in this opinion.

     The opinions herein are given as of the date hereof solely in connection
with the Notes to be issued by KDB and solely for the benefit of KDB and its
legal advisers (including United States counsel to KDB in connection with the
issue and sale of the Notes), and, except with our express consent, our opinions
herein may not be relied upon as of any later date for any other purpose or by
any other person.


                                     II-19



         We hereby consent to the use of this opinion letter as an exhibit to
the Registration Statement. In giving this consent, we do not hereby claim or
otherwise acknowledge or admit that we are within the category of persons whose
consent is required under Section 7 of the Securities Act.
