Chinas top leader warned that Beijing will go after so-called

platform companies that have amassed data and market power, a sign that the months-long crackdown on the countrys internet sector is only just beginning.

President Xi Jinping on Monday chaired a meeting of the communist partys top financial advisory and coordination committee, ordering regulators to step up oversight of internet companies, crack down on monopolies, promote fair competition and prevent the disorderly expansion of capital,

according to state broadcaster CCTV. Internet companies need to enhance data security and financial activities need to come under regulatory supervision, CCTV also reported.

The unusually strongly worded comments from Xi and his lieutenants suggest Beijing is preparing to amplify a campaign to curb the influence of its largest and most powerful private corporations, which has so far centered mainly on Jack Mas

Alibaba Group Holding Ltd. and its affiliate Ant Group Co. The term platform economies could apply to a plethora of mobile and internet giants that offer services to hundreds of millions, from ride-hailing behemoth Didi Chuxing to food delivery giant Meituan and e-commerce leaders like JD.com Inc. and Pinduoduo Inc.

Some platform companies are developing in non-standardized ways and that presents risks, CCTV said, citing minutes of the meeting. It is necessary to accelerate the improvement of laws governing platform economies in order to fill in gaps and loopholes in a timely fashion.

China Presses Alibaba to Sell Media Assets, Including SCMP

The report came days after Bloomberg News reported that governments watchdogs were now setting their sights on

Tencent Holdings Ltd.s $100 billion-plus finance empire after ordering an overhaul of Ant. Top financial regulators see Tencent as the

next target for increased supervision, according to people with knowledge of their thinking. Like Ant, Tencent will probably be required to establish a financial holding company to include its banking, insurance and payments services, said one of the people, seeking anonymity as the discussions are private.

The two firms will set a precedent for other fintech players on complying with tougher regulations, the people added. Such a move would mark a significant escalation in Chinas campaign to curb the influence of its technology moguls, which began last year with the scuttling of Ants $35 billion initial public offering and the publication of new antitrust regulations governing technology firms.

Tencent lost more than $65 billion of value in the two days following the report, though its shares were up more than 1% on Tuesday.

The development of Chinas platform economy is currently at a crucial stage, Xi said at Mondays meeting. It is necessary to focus on the long term, strengthen weaknesses and create an innovative environment to promote the healthy and sustainable development of the platform economy, he added.

The semi-regular meeting of the Partys top financial supervisory group typically helps to set the tone and direction of national policy. During their last gathering in September, Xi focused on the so-called dual circulation approach of relying on both international and domestic consumption and production to lift the economy.
