A longtime leader in Asia, O’Melveny helps clients navigate commercial matters critical to their businesses.

Our local team represents clients from around the world in a broad range of matters, including cross-border disputes, joint ventures, complex mergers and acquisitions, financings, investment and capital market transactions, investment fund formation, international trade and regulatory matters, and restructurings and insolvencies. The firm’s experience in Asian countries has produced a wealth of government, business and legal relationships that generate valuable insights for our clients.

We have a multiple award-winning China practice, with offices in Beijing, Shanghai, and Hong Kong. We also maintain a thriving practice in Tokyo, where we opened an office in 1987, and a strong presence in Southeast Asia with an office in Singapore. Following the opening of the Korean legal market, we established a “foreign legal consultant office” in Seoul, a natural outgrowth of our long history of representing Korean clients. Today, we’re among the most active international law firms in Korea.

We are immersed in the culture and practices of Asia. Many of our lawyers are native speakers of Asian languages, including Korean, Mandarin, Cantonese, and Japanese. Our lawyers also have strong knowledge of local laws and collectively have legal practicing qualifications spanning China, Hong Kong, Japan, Korea, and Singapore. In addition, many have practicing qualifications and experience in the United States, England, and other Western jurisdictions, including a strong team of UK-trained solicitors and barristers.
