TikTok and WeChat will be banned in the US from Sunday, unless President Trump agrees to a last-minute deal.
The Department of Commerce said on Friday it would issue an order barring US citizens from downloading messaging app WeChat or video-sharing app TikTok.
The order will ban the apps from being distributed through any app store on any platform.
The government is concerned the Chinese-owned apps could threaten national security.
If a partnership between Oracle and TikTok owner ByteDance is agreed – and approved by President Trump – the app would not be banned.
It is not yet clear whether Mr Trump will approve the deal, but he is expected to review it before the Sunday deadline.
