Chinese-owned social media platform TikTok yesterday announced it would pull out of Hong Kong within days, as global tech giants struggle to figure out how to operate in the city under sweeping new security rules imposed by Beijing.
Major US internet companies including Facebook, Microsoft, Google, Twitter and Zoom have all announced they have suspended the processing of requests for user data from the Hong Kong authorities while they study the new law.
The US companies' social media platforms are generally banned in China, where access is blocked by Beijing's "great firewall". Most have operated freely in Hong Kong, but will now have to determine how to comply with new rules for the city, which rights groups say threaten freedoms enjoyed for decades.
Facebook, which also owns WhatsApp and Instagram, said in a statement on Monday it was pausing reviews of user data requests for all of its services "pending further assessment of the National Security Law."
Google and Twitter said they had suspended their reviews of data requests from Hong Kong authorities immediately after the law went into effect last week. Zoom and Microsoft's LinkedIn issued similar statements yesterday.
US Secretary of State Mike Pompeo said on Monday Washington was considering banning TikTok in the United States. Asked if Americans should download it, he told Fox News: "Only if you want your private information in the hands of the Chinese Communist Party."
China's parliament passed the national security legislation last week, setting the stage for the most radical changes to the former British colony's way of life since it returned to Chinese rule 23 years ago.
Hong Kong late on Monday published more details about how the new law will strengthen police powers over the internet, including the ability to ask publishers to remove information deemed a threat to national security.
Asked about the moves by the US tech firms, Hong Kong Chief Executive Carrie Lam told a news conference yesterday: "Ultimately, time and facts will tell that this law will not undermine human rights and freedoms."
