Also on Thursday, Alibaba announced it would formally take a stake in its affiliated business unit, Ant Financial which operates the massively popular Ali Pay mobile payment application and credit scoring unit Sesame Credit, among other financial services businesses.
Alibaba said it would acquire newly issued shares from Ant Financial in exchange for certain intellectual property rights held by Alibaba but connected to Ant Financial.
The step is a sign that Ant Financial is on a path to its own public listing soon, with Alibaba's equity stake likely to resolve some lingering legal issues.
In 2016, Ant Financial raised $4.5 billion at a roughly $60 billion valuation.
