Beijing, China - China on Monday urged the US to listen to "rational voices" over the social media platform TikTok, as a law banning the wildly popular app on national security grounds came into effect.

"We hope that the US side will seriously listen to rational voices and provide an open, fair, just, and non-discriminatory business environment for market entities from all countries operating in the United States," foreign ministry spokesperson Mao Ning said.

"TikTok has been operating in the United States for many years and is deeply loved by American users," Mao said.

"It has played a positive role in promoting domestic employment and driving consumption in the US," she added.

China US trade envoy says China's shipbuilding policies warrant "urgent action"

TikTok restored service in the US Sunday after briefly going dark, crediting President-elect Donald Trump, who retakes power on Monday, for making the reversal possible.

The outgoing administration of President Joe Biden had earlier said that it would not enforce any ban.

TikTok had shut down in the US late Saturday as a deadline loomed for its Chinese owners ByteDance to sell its American subsidiary to non-Chinese buyers.

Trump has promised to issue an executive order delaying the ban to allow time to "make a deal" to remove TikTok's US subsidiary from Chinese ownership.
