Xi and Kim met in the northeastern city of Dalian in an unannounced visit by the North Korean leader on May 8. Trump said the meeting between the two leaders was not a great meeting as there has been a change in North Korea's attitude after that.
"I think that President Xi is a world class poker player. I probably maybe doing the same thing that he would do. But I will say this, there was a somewhat different attitude after that meeting, and I'm a little surprised," Trump told reporters at the White House.
"Now maybe nothing happened, I'm not blame anybody. But I'm just saying maybe nothing happened and maybe it did. But there was a different attitude by the North Korean folks after that meeting. So I don't think it was a great meeting," Trump said.
Nobody knew about the meeting and all of a sudden it was reported that he was in China a second time, he said.
"The first time everybody knew about, the second time was like a surprise. And I think things changed after that meeting. So I can't say that I'm happy about it," Trump said in presence of South Korean President Moon Jae-in.
"The second meeting I think there was a little change in attitude from Kim Jong-un", he said. "Hope that's not true, because I have a great relationship with President Xi. He's a friend of mine, he likes me, I like him. I mean that was two of the great days of my life being in China. I don't think anybody's ever been treated better in China in their history," he said.
"It was an incredible thing to see. We built a very good relationship, we speak a lot. But there was a difference when Kim Jong-un left China the second time. And I think they were dedicating an aircraft carrier that the United States paid for," Trump said.
