(Reuters) -TikTok plans to shut its app for U.S. users from Sunday, when a federal ban on the social media app could come into effect, unless the Supreme Court moves to block it, sources familiar with the matter said.

The U.S. Supreme Court is viewed as open to upholding a national-security law that will shut down the video-sharing app nationwide on Sunday if it continues to be controlled by its Chinese parent company.

Users of the Chinese social media app RedNote welcomed "TikTok refugees" from the United States with selfies and messages on Wednesday, as Beijing said it encouraged stronger cultural ties with other countries in response to the sudden influx.
