President Donald Trump said Monday he expects a second summit with Kim Jong Un to take place “quite soon” as he returned to the United Nations to trumpet a turnaround in ties with the North Korean leader.

Trump used his debut address to the UN General Assembly last year to threaten to “totally destroy” North Korea and belittled Kim as “rocket man”, prompting Kim to respond by calling the US president “mentally deranged”.

But speaking as he arrived at UN headquarters in New York for this year’s gathering, Trump hailed “tremendous progress” to halt Pyongyang’s nuclear and ballistic missile tests and said that a year later it was a “much different time.”

“It looks like we’ll have a second summit quite soon,” he told reporters.
