Yulchon Rehires Former Prosecutor and Presidential Office Counsel Yung Sang LEE 

to Strengthen Cross-Border Investigations and Corporate Risk Advisory Service

Press Release - Yulchon announced the return of former senior prosecutor and corporate investigations lawyer Yung Sang LEE as a partner in the firm’s Global White-Collar Defense Team.

Lee rejoins Yulchon after serving in a series of senior public and private sector roles, including the Office of the President. His practice will focus on criminal and regulatory investigations, compliance, and multinational client services.

Widely regarded as one of Korea’s leading corporate investigations practitioners, Lee brings nearly two decades of experience spanning prosecution, government policy, multinational corporate compliance, as well as private corporate practice.

Prior to rejoining Yulchon, Lee served as International Legal Affairs Secretary and Legal Affairs Secretary at the Office of the President. He also served as Vice President at Coupang, where he advised on corporate legal risk, compliance, and regulatory matters. Earlier in his career, Lee held various prosecutorial positions, including at the Supreme Prosecutors’ Office, the Ministry of Justice, and the Seoul Central District Prosecutors’ Office.

“Today’s corporate risk environment requires more than traditional litigation capability,” said Seok Hoon KANG, Chairman and Managing Partner. “Clients increasingly need counsel who can integrate investigations, regulatory response, compliance strategy, government policy insight, and cross-border coordination into a single risk-management framework. Mr. Lee is uniquely positioned to deliver that level of strategic and international perspective."

The firm noted that Lee’s background is particularly differentiated in the Korean legal market, combining experience across the prosecution service, government, private practice, and multinational corporate environments. His experience includes handling international criminal cooperation matters with the US Department of Justice, extradition, asset recovery, anti-money laundering matters, and investigations involving overseas funds and cartel conduct.

During his previous tenure at Yulchon, Lee advised on a range of complex corporate investigations and crisis-management matters, including cases involving parallel investigations in Korea and overseas jurisdictions, conflicting regulatory standards across multiple countries, and matters concerning alleged involvement of foreign headquarters in domestic investigations.

Lee is also expected to play a significant role in Yulchon’s expanding cross-border investigations and global compliance work, as multinational enforcement cooperation and international regulatory scrutiny continue to intensify.

Yulchon added that Lee has consistently received strong client feedback for his hands-on approach to investigations and crisis management, particularly from multinational companies that valued his clear communication and practical problem-solving capabilities.
