Trump On Way To 'Mission of Peace' In North Korea

Trump says he is feeling very positive ahead of the summit

U.S. President Donald Trump says North Korean leader Kim Jong-Un has a "one-time shot" at peace ahead of the pair's much-anticipated summit on Tuesday.

Speaking at the G7 Summit in Canada just before embarking on his journey to Singapore, Trump said he would know "within the first minute" whether North Korea was serious about reaching a deal with the U.S.

"Just my touch, my feel. That's what I do," he said.

Trump boasted North Korea had been "working very well" with the United States and he was "on a mission of peace" to achieve denuclearisation.

"In my heart we are going to be carrying the hearts of millions of people, people from all over the world," he said.

"We have to get denuclearisation . . . I think that North Korea will be a tremendous place in a very short period of time.

"I feel that Kim Jong-Un wants to do something great for his people and he has that opportunity . . . it's a one-time shot."

President Donald Trump had railed against trade practices he called unfair to the United States at the Group of Seven nations summit where leaders agreed to fight protectionism and reform the World Trade Organisation.

"We're like the piggy bank that everybody is robbing," Trump said.

"It's going to stop now or we'll stop trading with them (other nations)."

Trump flew by helicopter to the Canadian air base at Bagotville before boarding Air Force One and  leaving for Singapore, where he was scheduled to arrive late on Sunday.
