Starbucks China has appointed Leo Tsoi as its new CEO, and promoted Molly Liu to chief operating officer, both roles effective October 1.

Leo Tsoi has been working as Starbucks China’s COO and president of Starbucks Retail for the last five years. Under Tsoi’s management, the coffee chain has grown its footprint across the Chinese mainland to 5200 stores in more than 200 cities.

As one of the leading architects behind Starbucks China’s growth since he rejoined the company in 2012, Tsoi previously held several leadership positions, including VP of North China region, chief marketing officer, and VP of Store Development and Design.

He has also engineered the development of the China store portfolio by pioneering new store concepts, which “have influenced new coffee-inspired lifestyles and further elevated third place experiences for Starbucks customers in China,” the company said in a statement.

Belinda Wong will continue to serve as chairman of Starbucks China, focusing her attention toward delivering a holistic, long term strategy for Starbucks in the market, driving innovation through Starbucks Siren Ventures in China and other partnership opportunities, as well as elevating social impact in local communities through the Beijing Starbucks Foundation, the company said.
