Alibaba Group founder Jack Ma, who helped launch China’s online retailing boom, stepped down as chairman of the world’s biggest e-commerce company Tuesday at a time when its fast-changing industry faces uncertainty amid a U.S.-Chinese tariff war.
Ma, one of China’s wealthiest and best-known entrepreneurs, gave up his post on his 55th birthday as part of a succession announced a year ago. He will stay on as a member of the Alibaba Partnership, a 36-member group with the right to nominate a majority of the company’s board of directors.
Ma, a former English teacher, founded Alibaba in 1999 to connect Chinese exporters to American retailers.
The company has shifted focus to serving China’s growing consumer market and expanded into online banking, entertainment and cloud computing. Domestic businesses accounted for 66% of its $16.7 billion in revenue in the quarter ending in June.
