Alibaba Group chief executive Eddie Wu has been named as the new chief executive of its domestic ecommerce arm Taobao and Tmall Group.

The company said Wu will take on the role with immediate effect, strengthening his direct control over the China-based group’s core businesses.

Wu has been group CEO since September and has also taken over from previous head Daniel Zhang as the company’s cloud business chief executive.

His latest role means he will now lead the overall group as well as the cloud division and domestic ecommerce.

Wu replaces Trudy Dai, formerly the Taobao and Tmall Group chief executive, and she will move to assist in establishing a new asset management company, an Alibaba spokesperson confirmed.

In a letter seen by Reuters and signed by group chair Joseph Tsai, Dai’s shift in role is described as “part of ongoing efforts to improve return on capital”.

In a post-earnings call last month, Wu briefed analysts about Alibaba Group’s future strategy and said the company would undergo a review to create “core” and “non-core” businesses.

“Core businesses are where we will keep our long-term focus, intensively invest resources, pursue R&D, enhance user experience,” he said.

In March, Alibaba was divided into six units as part of the largest restructuring in the company’s history.
