LEI LI is the managing partner of Sidley's Beijing office. Since 2007, Lei has been advising companies on a broad range of regulatory, compliance, and government enforcement matters in China and international markets, with a particular focus in the high-tech and life sciences industries, and is one of the most respected legal practitioners in China in his areas of practice.
In the life sciences field, Lei is the co-head of Sidley’s renowned China Life Sciences Practice, which has set the record of winning the “Band 1” ranking by Chambers in the “Life Science – Greater China Region” category 15 years in a row since it was launched (2010 to 2024). For over a decade, Lei has advised multinational and local Chinese pharmaceutical and medical device companies on all types of matters across the full spectrum of the industry and has handled some of the largest and most representative matters in the industry in China in the last decade.
Lei is a seasoned antitrust lawyer, and has practiced antitrust law in China (i.e., the Anti-monopoly Law) since its inception in 2008. Lei has focused his antitrust practice on regulatory compliance, internal investigations and government investigations. Particularly, he has acted as the lead external counsel to his clients in several high-stake antitrust inquiries and investigations launched by the central and provincial antitrust authorities in China, all in the high-tech and life sciences industries.
Lei has extensive experience in all types of anti-corruption compliance and investigation matters in China. Representing both multinational companies and local Chinese companies, he has handled a large number of government anti-corruption investigations under both Chinese laws and the U.S. Foreign Corrupt Practices Act (FCPA), including representing corporations in several high-stake civil and criminal investigations by the U.S. Securities and Exchange Commission (SEC) and the U.S. Department of Justice (DOJ). He also has advised a large number of companies in setting up their anti-corruption compliance and internal control programs in China.
Prior to joining the firm, Lei worked at the central government of China (Ministry of Commerce, MOFCOM) for eight years (1998 to 2006) as a senior attorney handling inter-governmental trade and investment disputes and guiding Chinese companies’ response to complex cross-border litigation. Since joining the firm, Lei has continued this practice and advised a large number of Chinese companies in various types of regulatory, enforcement and litigation matters in the U.S. and EU, with a particular focus on international trade compliance and investigation matters. In the trade defense area, Lei and the Sidley team advised Chinese solar panel manufacturers in the decade-long anti-dumping and countervailing investigations initiated by the U.S. and EU governments, which was the largest trade defense investigation in the world’s history, in addition to several other major trade defense cases (most recently, the EU’s anti-subsidy investigation on electric vehicles from China). In the economic sanction, export control and customs law areas, Lei has been advising major Chinese high-tech companies in dealing with highly complex regulatory license and approval matters in the U.S. and EU, as well as government investigation and enforcement matters, including a few criminal investigations in the U.S.
