North Korea marked the start of the advent season on Tuesday with the promise of a "Christmas gift" for the U.S. if it made no progress on reviving stalled nuclear talks in December.
But during a press conference at the US Ambassador's residence in London, Mr Trump took the opportunity to boast of his dealings with North Korea in disarmament talks while also making a scathing assessment of his predecessor.
There are plans for talks before the new year's negotiations deadline, but North Korea has sent a fresh warning to President Trump today in an attempt to secure concessions.
In May, after news that North Korea tested new ballistic weapons, Trump said, "North Korea fired off some small weapons, which disturbed some of my people, and others, but not me".
"The dialogue touted by the United States is, in essence, nothing but a foolish trick hatched to keep the DPRK bound to dialogue and use it in favor of the political situation and election in the USA".
"What is left to be done now is the US option and it is entirely up to the USA what Christmas gift it will select to get", Ri said.
Working-level talks held in Sweden in October broke down over what the North Koreans described as the Americans' "old stance and attitude".
Kim had "worked heart and soul to turn Samjiyon County, the sacred place of the revolution, into the utopia town under socialism", the official KCNA news agency said.
Joshua Pollack, the editor of the Nonproliferation Review, pointed out that Pyongyang has used the threat of a "gift" before, to refer to its first test launch of an intercontinental ballistic missile (ICBM) in 2017. He was apparently alluding to the North's suspension of nuclear and long-range missile tests since 2017. "That's why I call him Rocket Man", the president said.
The latest test involved a super-large multiple rocket launcher last week. He definitely likes sending rockets up, doesn't he?
"My relationship with Kim Jong-un is really good, but that doesn't mean he won't abide by the agreement we signed", Trump said. He expressed "confidence that Chairman Kim will keep his promise to me". When a journalist put it to him that Kim continued to developed both programmes, the president replied "You don't know that", even though it reflects the United States intelligence consensus.
Any major actions from Kim may be announced on January 1, a date when North Korean leaders typically deliver a New Year's address that lays out the policy priorities for one of the world's most reclusive states. "We'll see. We'll see what happens".
