The tech company has revealed it intends to stop operations of the TikTok app in Hong Kong after China implemented a new security law on the city.
The move comes on the back of a number of other big-name brands - such as Facebook, WhatsApp, Twitter and Google - also announcing plans to make changes to their operations in Hong Kong.
However, Hong Kong's leader Carrie Lam has defended the recent change in legislation, saying it was needed in order to restore order in the city following anti-China protests in recent months.
She said: "Compared with the national security laws of other countries, it is a rather mild law. Its scope is not as broad as that in other countries and even China."
Meanwhile, US Secretary of State Mike Pompeo has revealed that the government is "certainly looking at" banning Chinese social media apps following the law change.
He told Fox News: "I don't want to get out in front of the President (Donald Trump), but it's something we're looking at."
In response, a TikTok spokesperson said: "TikTok is led by an American CEO, with hundreds of employees and key leaders across safety, security, product, and public policy here in the US.
"We have no higher priority than promoting a safe and secure app experience for our users. We have never provided user data to the Chinese government, nor would we do so if asked."
