The firm's China-based attorneys offer a wide array of legal services and work closely with their colleagues in the U.S. and Europe to leverage the firm's experience and resources on a global scale. Led by an experienced team of Greater China-based partners who are recognized experts in U.S. and Hong Kong capital markets, private equity, M&A, and corporate governance, our fully integrated group has more than 50 bilingual professionals. Drawing on Wilson Sonsini's comprehensive platform of practice areas and industry groups, our firm also represents both U.S.- and Asia-based companies and funds in corporate, private equity, and venture capital investments; joint ventures; technology transactions; IP matters; antitrust counseling; arbitration; and litigation. Of note, the attorneys in the firm's Hong Kong office advise clients on matters governed by both U.S. and Hong Kong laws.

In addition, our attorneys' deep and nuanced understanding of China's business and political landscapes, as well as its culture, makes the firm an ideal partner for companies, private equity and venture capital funds, and financial institutions in the region.
