Trump says U.S.-China trade deal will be signed on Jan 15

U.S. President Donald Trump said on Tuesday that Phase 1 of an American trade deal with China would be signed on Jan. 15 at the White House.

The president wrote in a tweet that he would sign the deal with "high-level representatives of China" and that he would later travel to Beijing to begin talks on the next phase.

The deal on the first phase was struck in December.
