Re:        The Republic of Korea: US$500,000,000 2.00% Notes due 2024;

US$1,000,000,000 2.50% Notes due 2029

Ladies and Gentlemen:

We have acted as Korean counsel for The Republic of Korea (the “Republic”), in connection with the Republic’s offering pursuant to a registration statement filed with the United States Securities and Exchange Commission (the “Commission”) on Schedule B (file number: 333-231096) of the Securities Act of 1933, as amended (the “Securities Act”) when it became effective (the “Registration Statement”) of US$500,000,000 aggregate principal amount of 2.00% notes due 2024 (the “2024 Notes”) and US$1,000,000,000 aggregate principal amount of 2.50% notes due 2029 (the “2029 Notes”, and together with the 2024 Notes, the “Notes”) to be issued under the fiscal agency agreement dated as of April 17, 1998, as amended by the Amendment No.1 thereto (the “Amendment No.1”), dated June 3, 2003, and the Amendment No.2 thereto (the “Amendment No.2”), dated July 17, 2018 (such fiscal agency agreement, as amended by the Amendment No.1 and the Amendment No. 2, being referred to as the “Fiscal Agency Agreement”) between the Republic and The Bank of New York, as fiscal agent. The prospectus dated May 15, 2019 (the “Base Prospectus”), relating to the Notes to be issued by the Republic pursuant to the Registration Statement, as supplemented by the final prospectus supplement, dated June 12, 2019 used in connection with the offering of the Notes, is herein called the “Prospectus”.

We have examined all such laws and regulations of the Republic as are relevant to the Fiscal Agency Agreement and the Notes and the originals or copies, certified or otherwise identified to our satisfaction, of all such official records of the Republic, and orders of officials and agencies of the Korean government, of all such certificates of officials and other representatives of the Republic, and of all such other agreements, documents and matters as we have deemed necessary or advisable for the purposes of this opinion.

In such examination, we have assumed the genuineness of all signatures, seals and stamps, 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, and we have found nothing to indicate that such assumptions are not fully justified.

In giving this opinion, we have also assumed in relation to the documents which we examined that other than in relation to the Republic, all such documents are within the capacity and powers of and have been validly authorized, executed and delivered by the parties thereto, and are legal, valid, binding and enforceable in accordance with their respective terms under the laws of the State of New York by which they are expressed to be governed, and that all necessary governmental consents, authorizations and approvals required in any country (other than the Republic) for the execution, delivery and performance by any parties (other than the Republic) to the Fiscal Agency Agreement and the Notes have been or will be obtained and that all necessary notices, filings, registrations and recordings in any applicable jurisdiction (other than the Republic) in respect of the Fiscal Agency Agreement and the Notes have been or will be given or effected in accordance with the laws and regulations of every such applicable jurisdiction. As to any other matters of fact material to the opinions expressed herein, we have relied upon certificates or statements of officials and other representatives of the Republic.

June 19, 2019

Page 2

Based upon the foregoing and subject to further qualifications set forth below, we are of the opinion that:

1. The Fiscal Agency Agreement has been duly authorized and executed by the Republic;

2. The statements in the Prospectus concerning matters of Korean law (except for the financial and statistical data contained therein as to which we express no opinion) are accurate and up-to-date as of the date hereof in all material respects; and

3. The Notes have been duly authorized, executed, issued and delivered by the Republic and constitute valid and binding obligations of the Republic and enforceable in accordance with their terms.

We are admitted to practice law in the Republic, and this opinion is given with respect to the laws of the Republic as currently in effect and we do not pass upon and we express no opinion in respect of those matters governed by or construed in accordance with the laws of the United States of America or the State of New York or the laws of any jurisdiction other than the Republic. To the extent that the laws of the United States of America and the State of New York are relevant to our opinions set forth above, we have, without making any independent investigation with respect thereto, relied upon, subject to the qualifications, assumptions and exceptions set forth in, the opinions of Cleary Gottlieb Steen & Hamilton LLP, United States counsel to the Republic, filed with the Commission on June 19, 2019. We have also assumed that there is nothing in the law of any jurisdiction other than the Republic which affects this opinion.

The opinions set forth above are subject to the following: (a) with respect to the Fiscal Agency Agreement, we have assumed that such collective action clauses as set forth in Section 13 and 14 of the Fiscal Agency Agreement are legal, valid and enforceable under the laws of the State of New York which is stated to govern the Fiscal Agency Agreement and we note that there is no express provision provided under the National Bond Act of the Republic in respect of the collective action clauses as set forth in Section 13 and 14 of the Fiscal Agency Agreement nor is there any Korean court precedent dealing with this issue; (b) the obligations of the Republic under the Fiscal Agency Agreement and the Notes may be limited or affected by the laws governing fraudulent conveyance, moratorium, statutory limitation or other similar matters which generally affect the rights of creditors; (c) the obligations of the Republic under the Fiscal Agency Agreement and the Notes may be also affected or limited by the general principle of good morals and other social order and the general principle of good faith and fairness provided for in the Civil Code of the Republic; (d) nothing herein should be taken as indicating that the remedies of specific performance or injunction would necessarily be available with respect to any particular provision of the Fiscal Agency Agreement and the Notes and any related agreements in any particular instance; (e) the enforceability of provisions releasing or exculpating a party from, or requiring indemnification of a party for, liability for its own action or inaction may be limited or affected where the action or inaction involves unlawful conduct, willful misconduct or gross negligence; (f) Korean courts may exercise judicial discretion in determining such matters as conclusiveness of certificates, amount of damages and entitlement to attorneys’ fees and other costs; (g) failure to exercise a right of action for more than a certain period of time may operate as a bar to the exercise of such right, and failure to exercise such a right for a certain period of time may, under certain circumstances, be deemed by the Korean courts to constitute a waiver thereof; and (h) if the Korean government deems that certain emergency circumstance, including but not limited to severe and sudden changes in domestic or overseas economic circumstances, extreme difficulty in stabilizing the balance of payments or in implementing currency, exchange rate and other macroeconomic policies, has occurred or is likely to occur, it may impose certain necessary restrictions provided for under the Foreign Exchange Transaction Act and the rules and regulations promulgated thereunder, such as the suspension of payments or requiring prior approval from governmental authorities for any transaction.

Furthermore, we assume no obligations to advise you, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the views expressed herein.

The Republic of Korea

Ladies and Gentlemen:

We have acted as special United States counsel to the Republic of Korea (the “Republic”) in connection with the Republic’s offering pursuant to a registration statement under Schedule B (No. 333-231096) of US$500,000,000 2.000% notes due 2024 (the “2024 Notes”) and US$1,000,000,000 2.500% notes due 2029 (the “2029 Notes” and, together with the 2024 Notes, the “Notes”) issued under a fiscal agency agreement dated as of April 17, 1998, as amended by amendment no. 1 thereto dated as of June 3, 2003 and Amendment No. 2 thereto dated July 17, 2018 (the “Fiscal Agency Agreement”), between the Republic and The Bank of New York Mellon, as fiscal agent. Such registration statement, as amended when it became effective, is herein called the “Registration Statement;” the related prospectus dated May 15, 2019, as filed with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”), is herein called the “Base Prospectus;” the related prospectus supplement dated June 12, 2019, as filed with the Commission pursuant to Rule 424(b) 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) specimens of the Notes; 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 Republic and such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinion expressed below.

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 (i) the accuracy as to factual matters of each document we have reviewed and (ii) that the Notes conform to the specimens thereof that we have reviewed and have been duly authenticated in accordance with the terms of the Fiscal Agency Agreement.

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 Republic, entitled to the benefit of the Fiscal Agency Agreement.

In connection with the foregoing opinion, (a) we have assumed that each of the Republic 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 Republic 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 and (c) such opinion is subject to the effect of judicial application of foreign laws or foreign governmental actions affecting creditors’ rights. In addition, we note that (i) the enforceability of the waiver of immunities by the Republic set forth in the Notes is subject to the limitations imposed by the Foreign Sovereign Immunities Act of 1976 and (ii) the designation of the U.S. federal courts sitting in The City of New York as a venue for actions or proceedings relating to the Notes is (notwithstanding the waiver in such provisions) subject to the power of such courts to transfer actions pursuant to 28 U.S.C. § 1404(a) or to dismiss such actions or proceedings on the grounds that such federal court is an inconvenient forum for such action or proceeding. 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. §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 letter as an exhibit to the Registration Statement and to the reference to us under the heading “Legal Matters” in the Prospectus. In giving such consent, we do not thereby admit that we are experts with respect to any part of the Registration Statement, including this exhibit, within the meaning of the term “expert” as used in the Securities Act, or the rules and regulations of the Commission issued thereunder. We assume no obligation to advise you, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinion expressed herein.
