The eight-lawyer, white-collar and compliance group at YuandaWinston, the Chinese alliance firm of Winston & Strawn, has joined Chinese firm JunHe in Shanghai.

The team is led by compliance partners Leon Liu and Carol Sun, who will also be partners at JunHe. 

Liu, a compliance and investigations specialist, has been a partner at YuandaWinston since 2007 when he and a group of other lawyers broke away from AllBright Law Offices and founded the Shanghai-based law firm now known as Yuanda. The Chinese firm is known for its compliance and white-collar practice. 

From 2007 until June 2020, Yuanda was known to the international market as MWE China Offices, operating in a strategic alliance with Chicago-based McDermott Will & Emery. Ever since that strategic alliance, a first of its kind between a Western firm and a Chinese one, ended, the Chinese firm has been in a similar alliance with Winston & Strawn. 

A former prosecutor, Liu has built a practice advising multinationals on white-collar defense matters, government enforcement actions and internal investigations. He has advised, among others, Airbus, Akzo Nobel, Danone, GSK, Herbalife, Halliburton, KPMG, Medtronic, Merck and Walmart on multijurisdictional government enforcement and crisis matters. 

Sun joined Yuanda in 2017 from Dentons' Shanghai office, where she led the compliance practice. A cybersecurity and data privacy specialist, she has advised, among others, Ant Group, Citi Group, UnionPay International, ZTE, LVMH, BASF, GSK, Blizzard and Siemens Healthineers on complex data compliance challenges in both China and Western jurisdictions.

Liu and Sun's arrival will help strengthen JunHe's white-collar and regulatory compliance capability, particularly in the cross-border government enforcement, crisis management and data-related space. 

Warren Hua, JunHe's managing partner, said the compliance addition in Shanghai helps elevate the firm to a new level of meeting market demand and providing sophisticated services to both Chinese and Western multinationals. 

"JunHe formed a compliance practice group last year, teaming up over 30 partners. Now, we are so pleased to have Leon and Carol bringing their valuable practice to JunHe. We are eager and ready to introduce to our clients the integrated high-end service team with profound and market-leading experience," said Hua.

The compliance team exodus is the latest in a series of departures from YuandaWinston since the two firms entered into the alliance. In 2021, former partner Michelle Gon, who joined from McDermott when the alliance shifted, left for Chinese firm Han Kun Law Offices, while the former managing partner of Winston's legacy Shanghai office, Brinton Scott, left to join Holman Fenwick Willan in Shanghai.

No one from Yuanda or Winston & Strawn responded to requests for comments on the departures.
