Seokchun Yun

Partner at Lee & Ko (South Korea)

Speaker

Seokchun Yun is a partner in Lee & Ko’s International Arbitration & Cross-Border Disputes Practice Group. His practice focuses on international arbitration, investment treaty arbitration, international litigation, enforcement of foreign judgments and arbitral awards, international trade, international tax, foreign investment, construction and real estate disputes, and shareholder disputes involving complex cross-border elements.

Mr. Yun has represented sovereign states, state-owned enterprises, global private equity funds, and major multinational corporations in arbitration proceedings under the rules of leading arbitral institutions, including ICSID, ICC, LCIA, SIAC, HKIAC, ICDR, LMAA, JCAA, and KCAB, as well as in ad hoc proceedings. His investment treaty arbitration experience is particularly notable. He played a leading role in defending the Republic of Korea in the landmark Lone Star ICSID arbitration and related annulment proceedings, and also represented the State in proceedings before the English courts challenging the Elliott UNCITRAL investment arbitration award, securing complete victories for the Republic of Korea.

Mr. Yun’s practice is distinguished by the breadth of jurisdictions, legal systems, and international instruments involved in his matters. He has handled disputes and advisory matters implicating Korean, English, U.S. federal and state, Singapore, Hong Kong, Canadian, Australian, German, French, Italian, Swiss, Russian, Japanese, and Chinese law, as well as the CISG, UNIDROIT Principles, WTO rules, and investment treaties. This experience gives him particular strength in comparative legal analysis and in the strategic handling of disputes involving multiple legal regimes.

In addition to his extensive private practice experience, Mr. Yun brings a rare combination of law firm, in-house, and arbitral institution experience. He previously served as General Counsel of a leading autonomous-driving technology company and as Deputy Secretary-General of KCAB International. This background enables him to approach complex disputes with a practical understanding of both commercial realities and arbitral procedure.

Mr. Yun also has significant experience in cross-border enforcement, asset recovery, and international litigation. During his time at Kobre & Kim in New York, he worked on foreign judgment and arbitral award enforcement, asset tracing and recovery, and litigation before U.S. federal and state courts. He has also represented parties in international mediation proceedings before the Singapore International Mediation Centre and advised the Korean government in WTO dispute settlement matters.

Beyond his practice, Mr. Yun is actively involved in the arbitration and international law communities. He serves as Vice President of the Korean Association of Arbitration Studies, Research Director of the Korea International Trade Law Association, Public Relations Director of the Korean Private International Law Association, and Chair of the Americas Subcommittee of the Seoul Bar Association International Committee. He has taught Civil Procedure at Seoul National University College of Law and has authored or co-authored numerous books, treatises, journal articles, and international publications on arbitration, investment treaty disputes, international trade, and procedural law.
