"I don't think I have to prepare very much".
"From our point of view, it's important that the meeting take place, and that the meeting sets developments on a new trajectory ― one that will be conducive to the security and stability of the region", he said.
The jet landed at the airport Sunday afternoon amid huge security precautions on the city-state island.
According to BBC, before setting off, US President Trump described the summit as a "one-time shot" at peace and said the two were in "unknown territory in the truest sense".
Kim smiled broadly yesterday evening as he met Lee.
If nothing else, the process leading up to this meeting seems to have caused Kim to open up slightly, with, for example, the participation of North Koreans at the Winter Olympics in South Korea.
Mr Trump and Mr Kim have had an extraordinary up-and-down relationship over the past 18 months, trading insults and threatening war before abruptly changing tack and moving towards a face-to-face meeting.
Whatever Trump meant to gain with his strength would not be gained if Kim called off the talks in response. "We appreciated it", Mr. Trump said. The official was not authorized to speak publicly about internal deliberations and insisted on anonymity.
A Trump administration official, speaking on condition of anonymity, said the USA side was entering the talks with a sense of optimism and an equal dose of scepticism given North Korea's long history of developing nuclear weapons.
Last week, the Singapore government announced that the trade sanctions with North Korea would be temporarily lifted from June 9 to June 14 due to the US-North Korea summit.
"We continue to call on North Korea to completely, verifiably, and irreversibly dismantle all of its weapons of mass destruction (WMD) and ballistic missiles as well as its related programs and facilities", it said.
Kim held a meeting with Singapore Prime Minister Lee Hsien Loong ahead of the planned summit.
January 9: North and South Korean officials meet at a border village and agree on North Korea sending athletes and delegates to the Winter Olympics in the South. Hundreds of North Koreans go to the Pyeongchang Games in February, including Kim's sister, who conveys her brother's desire for an inter-Korean summit with South Korea's president.
On Monday, North Korean state media said Kim and Trump would discuss a "permanent and durable peace-keeping mechanism" on the Korean peninsula, denuclearisation of the peninsula and other issues of mutual concern. Following the meeting, Pompeo will then travel to South Korea and China to brief the country's leaders on the talks.
Even if brief, the meeting could potentially be the start of a broader dialogue between Trump and Kim. And then the statement was released on Saturday night, only to have Mr. Trump disavow it. Mrs. He has not left his country since taking office in 2011 other than to visit China and the South Korean side of the Demilitarised Zone on the border. Seeing Nobel Peace Prize laurels and eyeing potential to show up his critics at home and overseas, Trump is granting Kim the global legitimacy he's long sought in hopes of securing a legacy-defining accord.
Pyongyang has said it is willing to deal away its entire nuclear arsenal if the United States provides it with a reliable security assurance and other benefits. But many say this is highly unlikely, given how hard it has been for Kim to build his program and given that the weapons are seen as the major guarantee to his holding onto unchecked power.
