He expressed optimism about the unusually long overseas trip as he boarded Marine One for Joint Base Andrews, from where he departed for Hawaii.
"I think we're going to have great success," he told reporters. "We'll be talking about trade. We'll be talking about, obviously, North Korea."
Trump is scheduled to visit five countries after stopping in Hawaii: Japan, South Korea, China, Vietnam and the Philippines.
He hinted that the North Korea issue will occupy a large portion of his meetings with leaders there.
"We'll be enlisting the help of a lot of people and countries and we'll see what happens," he said. "But I think we're going to have a very successful trip. There is a lot of good will." SOURCE FROM THE YONHAP NEWS AGENCY.
