"China very much wants to make a deal," Trump told reporters in Washington just hours after his top economic adviser expressed caution about talk of a possible U.S.-China trade agreement.

"We've had a very good discussions with China, we're getting much closer to doing something," Trump said before departing the White House for a campaign event.

"I spoke with President Xi (Jinping) yesterday. They very much want to make a deal," Trump said.

"I think we'll make a deal with China, and I think it will be a very fair deal for everybody, but it will be a good deal for the United States."

Trump said he will discuss trade with Xi when the two meet for dinner on the sidelines of the G20 leaders' summit at the end of November in Buenos Aires, Argentina.
