(Reuters) - Chinese tech giant Tencent Holdings Ltd said a company executive is being investigated by authorities over allegations of "personal corruption", after a media report said the move was linked to sharing of personal data from its popular WeChat app.
The move comes amid Beijing's unprecedented crackdown on its home-grown internet platforms, which has ensnared some of its best technology innovators and private-sector champions over violations of anti-trust and data privacy rules.
Any violation of customer data protection rules would pile more pressure on the local technology companies, already dealing with heightened regulatory scrutiny after years of a laissez-faire approach.
The Wall Street Journal reported earlier that a Tencent executive has been held by Chinese authorities as part of an inquiry into a high-profile corruption case involving one of the country's former top law-enforcement officials.
"We can confirm that case relates to allegations of personal corruption and has no relation to Weixin or WeChat," Tencent said in a statement to Reuters.
Citing people familiar with the matter, the Journal reported that the executive, Zhang Feng, has been under investigation by China's anti-graft inspector since last year over alleged unauthorized sharing of personal data collected by Tencent's social-media app WeChat.
Tencent said in statement to Reuters that Zhang's case was not related to its international WeChat app or domestic Weixin platform. It declined to elaborate further.
"This is just one more instance of Beijing entrenching control over the large and powerful tech giants under its purview," LightSTream Research analyst Mio Kato, who publishes on Smartkarma, told Reuters.
"This seems like an extension of the previous anti-corruption campaign that was focused on the political structure."
The Journal report said Zhang was suspected of turning over WeChat data to former vice public security minister Sun Lijun, who is being investigated by Beijing for undisclosed violations of Communist Party rules. (https://on.wsj.com/2NdMuv9)
Investigators were looking at what type of data Zhang might have shared with Sun and what Sun might have done with it, the report said.
The report comes as Chinese regulators and state media are becoming increasingly vocal about infringement of consumer rights by tech companies, which use personal data to drive businesses - from selling products to acquiring customers.
Chinese technology companies have also come under pressure to double down on corruption investigations in recent years, as a result of President Xi Jinping's year-long anti-graft drive.
Tencent said earlier this month it had fired more than 100 staff over embezzlement and bribery incidents.
Shares in Tencent, which is the most valuable company in Hong Kong with more than $900 billion in market capitalization, fell as much as 1.6% after the Journal report but pulled back later to end down 0.5% in a positive broader market.
Zhang was referred to as a Tencent vice president in a 2018 statement released by the municipal government of Zhangjiakou, a city near Beijing. Tencent, however, told Reuters he was not a vice president or a senior executive, without elaborating.
The Journal said Zhang could not be reached for comment, and Sun didn't respond to a comment request sent through anti-graft inspectors, the Central Commission for Discipline Inspection (CCDI) and the State Council Information Office (SCIO).
The CCDI and SCIO did not immediately respond to Reuters request for comment.
