The boss of Chinese tech giant Tencent has had meetings with Beijing's antitrust regulators, in what may be another sign of crackdown on the country's digital economy.
Tencent is China's biggest social media and video games company and its Hong Kong's most valuable stock, with a market capitalization of $776 billion.
Sources say its founder, Pony Ma, visited the State Administration of Market Regulation office this month.
At the meeting - which the sources say Ma had requested - the two parties discussed how Tencent could better comply with antitrust regulations.
The sources also say officials are looking into monopolistic practices by Tencent's WeChat - China's most popular messaging app.
Tencent is not the first company to come into Beijing's crosshairs.
Late last year, an antitrust investigation was launched against billionaire Jack Ma's Alibaba business empire.
A blockbuster IPO for its Ant financial platform, set to have been the biggest in history, was also suspended by Chinese regulators.
Beijing has voiced concerns that tech firms have built market power that stifles competition, have misused consumer data and violated consumer rights.
