-North Korean policy is coming ahead of the historic summit between President Donald Trump and Kim Jong Un. A senior White House official said Trump was "feeling good" and that the summit was open-ended, adding: "They will talk for as long as they need to".
The foreign minister posted a selfie of him and a smiling Kim wearing his trademark dark Mao suit on Facebook. Pompeo, who has twice met Kim, insisted Monday that Trump is fully prepared for his meeting with the North Korean leader.
Arriving at the Marina Bay Sands at around 10pm, he waved and smiled at a small crowd that had gathered in the hotel foyer.
United States and North Korean officials were still meeting on the eve of the summit in an effort to bridge the gap between the two countries on how to substantively achieve North Korean denuclearization.
Before a row of alternating US and North Korean flags, the leaders shook hands warmly at a Singapore island resort, creating an indelible image of two unorthodox leaders as they opened a conversation that could determine historic peace or raise the specter of a growing nuclear threat.
A flight across the world later and Trump was in Singapore, preparing for an unprecedented summit with Kim that has raised hopes of bringing peace to the Korean peninsula.
Iran said Monday that it remains dubious about the prospects for talks between the United States and North Korea, and warned Pyongyang to be highly vigilant about Washington's promises. "If diplomacy does not move in the right direction, those measures will increase", he said.
Michael Kovrig, a senior adviser for northeast Asia at the International Crisis Group, said Pompeo's comment that Trump "recognised Chairman Kim's desire for security" signalled that the U.S. may offer formal security guarantees to Pyongyang in exchange for nuclear disarmament.
Mr Trump is set to finally come face to face with North Korean leader Kim Jong-Un as the summit gets underway at 11am AEST today (9am local time).
The relative speed with which state media reported on Kim's arrival suggests a some confidence that the meeting will go well - or at least well enough.
Kim was also quoted as saying that, "If the summit produces positive outcomes, then the Singaporean government's effort will be recorded in history forever". James Clapper, the former U.S. director of national intelligence, acknowledged in The New York Times that asking North Korea to give up its nuclear weapons as a precondition for better relations with the United States - the longstanding policy of several USA administrations - is a "dead end". "For the time being we can not be optimistic about the United States' behaviour, and the government of North Korea must approach this issue with absolute vigilance", he added. Trump left that summit early and, as he flew to Singapore, tweeted that he was yanking the US out of the group's traditional closing statement. Their hotels are cordoned off with heavy security.
Both sides are finalising preparations for Tuesday's historic forum in Singapore, which is due to kick off at 9:00am (local time). It heralded the summit as part of a "changed era".
Discussions would focus on "the issue of building a permanent and durable peace-keeping mechanism on the Korean peninsula, the issue of realising the denuclearisation of the Korean peninsula and other issues of mutual concern", KCNA said.
The White House, in the statement, said that the ongoing discussions between the United States and North Korea had moved faster than expected. None of this would happen immediately, but neither would North Korea offer to give up its nuclear weapons program up front. Eventually, the United States defined success down, bent nonproliferation rules it shaped despite vociferous global opposition, and welcomed India in from the cold.
When announcing the reinstatement of the June 12 U.S. -DPRK summit, Trump said, "It will be a beginning". "The process could be doomed before it begins".
