China on Thursday slammed the approval of a US bill that would ban TikTok unless it severs ties with its Chinese parent company, vowing that Beijing would "take all necessary measures" to protect the interests of its companies overseas.

Beijing's Commerce Ministry Spokesperson, He Yadong, made this known at a press conference on Thursday afternoon.

He added that the United States should also "provide an open, fair, just, and non-discriminatory environment for foreign companies to invest and operate in the United States.

TikTok has soared in popularity worldwide but its ownership by Chinese technology giant ByteDance, and alleged subservience to Beijing's ruling Communist Party, has fuelled concern in Western capitals.

The United States House of Representatives had overwhelmingly approved a bill that would force TikTok to divest from its parent company or face a nationwide ban.

The bill is yet to pass the Senate, where it is expected to face a tougher test in order to become law.
