The North has taken steps to dismantle both facilities, but still fallen short of US demands for complete and verifiable denuclearization.

“If you read the papers today, it came out to the surprise of a lot of people -- not a surprise to me -- that they don’t mind having people come over, the experts, and check the sites,” Trump said.

“We’re doing well,” he added, listing a series of North Korean goodwill actions, such as the return of US prisoners and remains of American soldiers from the 1950-53 Korean War.

Trump said he had a “great talk” with Chinese President Xi Jinping about North Korea, including what he alluded to as the reduction of Chinese trade across the border with North Korea.

“The border is holding. And they’ve been honorable. And they’re doing what they said they were going to do,” Trump said.

North Korea is under tight international economic sanctions for its nuclear weapons program, and the US has vowed not to lift them until the North denuclearizes.

“We haven’t taken sanctions off,” Trump said. “And hopefully, we’ll be able to when we’re down the road. We want to take the sanctions off. We want North Korea to be very successful.”

Trump boasted of his “very good” relationship with Kim.

“We are getting to a point where they really want to do something,” he said. “And we’re not going to have to worry about millions of lives being lost and nuclear weapons going up all over the place and flying over Japan and everybody else.”

Trump is expected to hold a second summit with Kim early next year, after the first summit in Singapore in June produced a statement committing the North to work toward “complete” denuclearization of the Korean Peninsula in exchange for security guarantees from the US.

“Let me tell you, we would be in a nuclear war right now if the right person didn’t come along,” Trump said. “So we’re doing well. We’re doing well.” (Yonhap)
