President Donald Trump said the U.S. and China are set to "come away with" a trade deal, as he is expected to meet Chinese President Xi Jinping later this week in South Korea during his Asia tour.

"I've got a lot of respect for President Xi and I think we're going to come away with a deal," Trump told reporters on Air Force One en route to Japan from Malaysia.

"We have China coming and its going to be very interesting."

Trump added he might sign a final deal on TikTok on Thursday.
