The president said Saturday that trade negotiations with the Japanese prime minister have been moving forward, specifically regarding beef and agriculture.

"Great progress being made in our Trade Negotiations with Japan," Trump tweeted Saturday. "Agriculture and beef heavily in play. Much will wait until after their July elections where I anticipate big numbers!"

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.

In addition to trade, Trump told the media that he and Abe also covered subjects including the military.
