President Donald Trump says a deal to find a new owner for social media app TikTok in the United States is done and that it has the blessing of China's President Xi Jinping.

On Thursday, Trump signed an executive order that declared his planned deal met the requirements of a law that had called for banning the app in the US unless it was sold by its Chinese parent company ByteDance.

In comments in the Oval Office, he and Vice-President JD Vance said a group of investors would buy TikTok's US operations to create a new company valued at $14bn (£10.5bn).

The deal has yet to be confirmed by ByteDance or the Chinese authorities.

For years US officials and lawmakers have argued that ByteDance's links to the Chinese government threaten national security.
