Kim signed a deal promising “complete denuclearisation” of the Korean Peninsula in a historic meeting with the US president in Singapore on June 12.
But a report by United Nations watchdog the International Atomic Energy Agency warned yesterday that “the continuation and further development” of North Korea’s nuclear programme was “cause for grave concern”.
Despite the claims, Mr Trump stated: “A lot of good things are happening.”
He said that he had been working on the North Korean issue for only three months, while his predecessors spent more than 30 years without having accomplished anything significant.
I have very good personal relations with Chairman Kim and I think that’s what holds it together.
Mr Trump told reporters on Monday: “I stopped North Korea’s nuclear testing. Japan is thrilled. What is going to happen? Who knows? We are going to see.”
The President also boasted of his relationship with Kim, saying: “I like him and he likes me.
“There’s no ballistic missiles going up, there’s a lot of silence. I have very good personal relations with Chairman Kim and I think that’s what holds it together.”
When asked if the two could meet again, President Trump said: “It’s most likely we will, but I just don’t want to comment.”
Rumours have spread that the two leaders could hold a second meeting at next month’s UN General Assembly in New York.
However, footage taken by a US satellite emerged earlier this month that appeared to show activity at a missile factory in Sanumdong.
Following his third visit to North Korea, US Secretary of State Mike Pompeo told a Senate committee hearing in July that Pyongyang was continuing to produce fuel for nuclear bombs.
