President Biden on Wednesday signed a law that would ban Chinese-owned TikTok unless it is sold within a year.
It is the most serious threat yet to the video-streaming app's future in the U.S., intensifying America's tech war with China.
Still, the law is not expected to cause any immediate disruption to TikTok, as a forthcoming legal challenge, and various hurdles to selling the app, will most likely cause months of delay.
The measure was tucked into a bill providing foreign aid for Israel, Ukraine and Taiwan. The law stipulates that ByteDance must sell its stake in TikTok in 12 months under the threat of being shut down.
