China’s antitrust regulators are considering levying a record fine against Alibaba exceeding the $975 million that Qualcomm Inc. paid in 2015 over anticompetitive practices, so far the largest in China’s corporate history, according to people with knowledge of the matter, The Wall Street Journal reported.

Those people said Alibaba also will be required to end a practice under which, regulators believe, the tech giant punished certain merchants who sold goods both on Alibaba and its rival platforms. The precise remedies Alibaba will have to take likely will be hammered out only after a decision is announced, according to one of the people.

In addition, regulators are weighing whether to require Alibaba to divest itself of some assets unrelated to its main online-retailing business. Once final, measures against Alibaba will need to be approved by China’s top leadership.
