President Donald Trump and North Korean leader Kim Jong Un converged on this island city-state Sunday ahead of one of the most unusual and highly anticipated summits in recent world history, a sit-down meant to settle a standoff over Pyongyang's nuclear arsenal. It will be the first meeting between a sitting USA president and a DPRK top leader.
The Trump-Kim summit is expected to cost about S$20 million ($15 million), Lee told Singaporean media on Sunday, with security costs representing about half the total.
Trump is set to meet with Lee on Monday.
For the US, the term means North Korea relinquishing nuclear weapons - but Pyongyang may agree to do so only if certain conditions are fulfilled, experts warn.
For the pariah state, denuclearizing the Korean Peninsula is a situation in which North Korea gives up nukes if the USA ends its alliances in Asia, its policy of extended deterrence and ground troops on the peninsula, Victor Cha, a Georgetown University professor and senior advisor at the Center for Strategic and International Studies said at a Washington event on Monday.
It is an extraordinary turnaround from the rhetoric of a year ago, when Trump threatened the North with "fire and fury" and Kim dubbed him a "mentally deranged USA dotard".
US Secretary of State Mike Pompeo says Monday's preparatory talks were moving quite rapidly and "and we anticipate that they will come to their logical conclusion even more quickly than we anticipated". Both leaders were greeted on arrival by Singapore Foreign Minister Vivian Balakrishnan.
It's unclear what Trump and Kim might decide Tuesday.
He would not say whether that included the possibility of withdrawing US troops from the Korean Peninsula, but said the context of the discussions was "radically different than ever before".
Trump has said he hopes to make a legacy-defining deal for the North to give up its nuclear weapons, though he has recently sought to minimize expectations, saying more than one meeting may be necessary.
The Rodong Sinmun newspaper, the mouthpiece of the ruling Workers' Party, devoted its first two pages and 16 photos to Kim's trip, including images of him boarding an Air China Boeing 747 for the journey. 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".
