Former Simpson Thacher & Bartlett Beijing partner Shaolin Luo has joined private equity client YunFeng Capital as general counsel.

Corporate-focused Luo has long handled M&A and private equity investments related to China. Luo co-led the Simpson Thacher team – with co-head of the Wall Street firm's M&A practice Alan Klein – that advised state-owned China National Chemical Corp on its $43bn (£32bn) acquisition of Swiss agribusiness giant Syngenta AG.

Earlier this year, Luo acted for video-sharing app developer Musical.ly on its $1bn (£746m) merger with Chinese content platform operator Bytedance.

Luo joined Simpson Thacher's Beijing office as counsel in 2006 from Chinese firm Fangda Partners, where he was an M&A partner. He made partner at Simpson Thacher in 2008.

Shanghai-based YunFeng Capital was co-founded in 2010 by Alibaba Group Holding chairman Jack Ma Yun and friend David Yu Feng, who previously ran advertising firm Shanghai Target Media Co.

The Chinese buyout firm has been a longtime client of Simpson Thacher. In 2014, the firm advised YunFeng Capital on raising a $1.1bn (£820m) China-focused fund. Last year, Simpson Thacher also represented YunFeng Capital's affiliate brokerage Yunfeng Financial Group on its $1.7bn (£1.2bn) acquisition of US insurer Massachusetts Mutual Life Insurance Co.

In 2016, former Simpson Thacher partner Leiming Chen became general counsel at Jack Ma-affiliated Ant Financial Services Group. Late last year, Simpson Thacher promoted Beijing-based corporate lawyer Wang Yang to partner.

In a deal announced on Friday, Wang co-led a team alongside Hong Kong-based head of Simpson Thacher's China practice Celia Lam, representing Ant Financial on a $14bn (£10.4m) funding round from investors such as Singaporean sovereign wealth funds GIC Pte and Temasek Holdings, as well as Washington DC-based private equity firm The Carlyle Group.
