HONG KONG -- Alibaba Group is undertaking another management reshuffle as its core businesses face increasingly intense competition, with Trudy Dai stepping down as CEO of e-commerce unit Taobao Tmall Commerce Group, the company's biggest source of revenue.
Dai, a former student of founder Jack Ma from his teaching days, will be replaced by Eddie Wu, Alibaba Group CEO and acting CEO of its cloud unit. Both Dai and Wu helped found Alibaba.
