China’s government said it would oppose possible US plans to force TikTok’s Chinese owner to sell the short-video app and warned such a move would hurt investor confidence in the United States.
Governments are worried TikTok’s owner, ByteDance, might give browsing history or other data about users to China’s government or promote propaganda and disinformation.
The Wall Street Journal reported US authorities were considering banning TikTok ban if ByteDance does not sell the company.
“If the news is true, China will resolutely oppose it,” a spokeswoman from the Chinese ministry of commerce, Shu Jiting, said.
She gave no indication what Beijing might do.
A forced sale “would seriously damage investors from multiple countries including China” and hurt “confidence to invest in the United States”, Ms Shu said.
TikTok is one focus of conflicts between China and other governments over technology and security that are disrupting processor chip, smartphone and other industries.
TikTok's chief executive, Shou Zi Chew, is due to make a high-profile appearance on Thursday before a US Congressional committee to make the case for why the hugely popular video-sharing app should not be banned.
The United States, the UK and New Zealand’s parliament have banned use of TikTok on government-issued phones.
India has banned TikTok and dozens of other Chinese apps, including the WeChat message service, on security and privacy grounds.
