U.S. Secretary of State Mike Pompeo, the former Central Intelligence Agency director, spent the morning preparing with his top advisers, aides said.
Spare a moment, as you anticipate one of the most unusual summits in modern history, to consider North Korea's leader as he left the all-encompassing bubble of his locked-down stronghold of Pyongyang on Sunday and stepped off a jet onto Singapore soil for his planned sit-down with US President Donald Trump on Tuesday.
North Korean forces invaded the South in 1950 and the ensuing war saw US -led United Nations troops backing Seoul fight their way to a stalemate against Pyongyang's forces - which were aided by Russian Federation and China - before the conflict ended in stalemate and an armistice which sealed the division of the peninsula.
Pompeo had earlier tweeted a photograph at breakfast with ambassador Kim, stating the U.S. position was unchanged: "We remain committed to the complete, verifiable, irreversible denuclearization of the Korean Peninsula".
Haas offers a useful warning, though, as people around the world settle in to watch the show in Singapore: "Virtually no North Korea analyst inside or outside of the US government" expects Kim to actually give up his nukes. "If diplomacy does not move in the right direction.those measures will increase". Why only potentially? That's because these two world leaders are not, strictly speaking, known to be very diplomatic - that is to say that they are in no manner of speaking, known to be very diplomatic at all.
Trump made the remarks at a working lunch with Singapore Prime Minister Lee Hsien Loong at the presidential palace Istana after their bilateral meeting during which the two leaders discussed everything from the summit preparations to the US' tariff threats.
"It's unknown territory in the truest sense but I really feel confident", Trump said.
"Welcomed Chairman Kim Jong-Un, who has just arrived in Singapore", Balakrishnan tweeted.
"I'm very optimistic that we will have a successful outcome from our meetings tomorrow", he said.
The US leader has whipsawed on expectations for the meeting, signalling that it could be the beginning of a "process" of several meetings, only to call it a "one-time shot" for peace as he embarked for Singapore.
Singapore has spent $S20 million hosting the summit, half of that on security costs, with Lee saying it was "in our profound interest" to contribute to such an worldwide endeavour.
Rodman announced on Twitter that he would be attending the summit in Singapore to give "whatever support is needed to my friends" referring to both Trump and Kim.
The North Korean leader then traveled to the St. Regis Hotel - where he will be staying for the duration of the visit - in his armored limousine, which arrived on a separate flight.
North Korean state media has confirmed that the leaders of North Korea and the USA will focus on ensuring permanent peace and a nuclear-free Korean Peninsula in Singapore. It heralded the summit as part of a "changed era". This isn't like the United States and Iran.
The summit's venue is the Capella hotel on Sentosa, a resort island off Singapore's port with luxury hotels, a Universal Studios theme park and man-made beaches.
-North Korea tensions back to last year's precarious state, or worse. Economic adviser Larry Kudlow told CBS News in Washington that "Kim must not see American weakness", adding that by criticizing new tariffs, Trudeau was "pouring collateral damage on this whole Korean trip".
