The secrecy of the North Korean leader's health is, apparently, paramount. Today, we start with a behind the scenes of the summit.
And until denuclearisation takes place, sanctions against North Korea would remain in place, he stressed.
The White House says Trump will address the media on Tuesday following his summit with Kim and depart Singapore at approximately 8 P.M. The president had been expected to leave Singapore on Wednesday morning.
Trump told reporters the Singapore summit is "really a get-to-know-you kind of situation". He told reporters he thinks he will know nearly immediately whether a deal can be made, saying: "I will know, just my touch, my feel".
This is a very high bar and probably unrealistic after one meeting.
At issue is whether Kim would be willing to abandon a nuclear weapons program that has advanced rapidly in recent years, posing an increasing threat to the USA and its allies. Trump has expressed some concern about China's influence. He credits his administration's "maximum pressure" campaign with getting Kim to the table.
US Secretary of State Mike Pompeo said Monday that the goal of the meeting was the "complete and verifiable denuclearization of the Korean peninsula", adding that the US had not received any firm commitment from Pyongyang on exactly what the two sides would agree to.
Security is tight ahead of the summit between two unpredictable men who in the past have threatened to destroy the other's country during the stand-off over North Korea's nukes. The Worm has visited North Korea on multiple occasions and competed on Celebrity Apprentice in 2013. "We now know they have a pretty good track record in these negotiations - a flawless track record of cheating every time, so that's the context we now face".
Trump hopes the landmark talks will kick-start a process that eventually see Kim give up his nuclear weapons in an irreversible manner that can be verified internationally.
While advisers say Trump has been reviewing briefing materials, the president insists his gut instincts will matter most when he gets in the room with Kim.
North Korea had also threatened to strike Guam, an American territory in the Pacific Ocean.
The meeting between Kim and Trump will mark a turnaround of relations between the two leaders after a long-running exchange of furious threats and insults.
The discussions between the United States and North Korea are ongoing and have moved more quickly than expected.
Iran said North Korea should be wary of negotiating with Mr Trump following his withdrawal from the landmark 2015 nuclear agreement. It will be hard to live up to an April tweet in which he declared, "We haven't given up anything & they have agreed to denuclearization", as if the ultimate deal were already done.
Who are the key players in the North Korea regime and how are they related to the Supreme Leader?
