US President Donald Trump will extend TikTok's deadline to find a non-Chinese buyer or face a ban in the United States by another 90 days, the White House said on Tuesday.

"President Trump will sign an additional Executive Order this week to keep TikTok up and running. As he has said many times, President Trump does not want TikTok to go dark," Press Secretary Karoline Leavitt said in a statement. (AFP)
