In a speech before businessmen at the U.S. ambassador's residence, Trump claimed that Japan has enjoyed a trade advantage, but that the two countries were working on a bilateral trade deal.

"I would say that Japan has had a substantial edge for many, many years but that's OK,” Trump said. “Maybe that's why you like me so much." He added that "we'll get it a little bit more fair." He suggested that removing barriers to U.S. exports to help achieve this goal.
