Don't think he is playing: Trump on Kim Jong un

US President Donald Trump today said that he does not think that North Korean leader Kim Jong un is playing, although previous administrations were "played like a fiddle" because the country had different leaders.

Trump was responding to a series of questions from reporters on the historic summit meeting between North and South Korean leaders.

"I don't think he's playing. No, I don't think he's playing. You know it's never gone like this, it's never gone this far. I don't think it's ever had this enthusiasm for somebody for them wanting to make a deal," Trump said.

"I agree, the United States has been played beautifully, like a fiddle, because you had a different kind of a leader. We're not going to be played, OK? We're going to hopefully make a deal, if we don't, that's fine," he said.

He praised Chinese President Xi Jinping for being extremely helpful.

"Lot of very positive things happened over the last 24 hours," he said.

"We're in total touch with both North Korea and South Korea. We'll be setting up a meeting very shortly. We have it broken down to probably two sites now, two or three sites, locations. And hopefully we're going to have great success, we'll see what happens," Trump said.

Kim and South Korean President Moon Jae-in met today signing an agreement to end their war and denuclearise the Korean Peninsula.

Vice President Mike Pence said the North Koreans coming to negotiations table without America giving any concession was a reflection that the intense pressure of sanctions was working.

"Any talks, promises, and assurances from North Korea will be met with reservation, vigilance, and verification. Planning for the United States and North Korea Summit continues, but as we've said before the pressure campaign will continue unabated," Pence said.

Top American lawmakers have welcomed the peace efforts between North and South Korea.
