President Donald Trump shakes hands with Singapore Prime Minister Lee Hsien Loong ahead of a summit with North Korean leader Kim Jong Un, June 11, 2018, in Singapore. The talks are expected to focus at least in part on an eventual deal to dismantle North Korea's nuclear program.
The other countries at the G-7 summit, however, rallied to Mr. Trudeau's support.
It "would instead lay out practical steps with requisite commitments from North Korea that demonstrate that it understands, accepts and is committed to achieving denuclearisation as the United States defines it", said Enos, who is also in Singapore to watch the proceedings.
Washington is demanding the complete, verifiable and irreversible denuclearization (CVID) of the North, while Pyongyang has so far only made public pledges of its commitment to the denuclearization of the peninsula - a term open to wide interpretation - while seeking security guarantees.
Yet the top United States diplomat added Trump is ready to offer "unique" guarantees to ease the regime's concerns about giving up a nuclear arsenal that provides a deterrent against foreign adversaries while also serving as a key point of national pride.
"We will have to provide security assurances, to be sure", Pompeo said on Fox News Sunday.
What was initially portrayed by the White House as a summit meant to completely rid the North of its nuclear weapons is now being cast as a chance to "start a dialogue" and for Trump the dealmaker to look into the eyes and take the measure of his nuclear-armed antagonist.
From there, the two will engage in more talks with advisers joining them through a working lunch.
In a statement, the White House said Mr Trump would speak to the media before departing for the USA at 8:00pm.
Exuding confidence, Trump said he has done relatively little formal preparation.
"I think within the first minute I'll know", Trump said.
In part, these lowered expectations are a reflection of the extreme skepticism among many that the North can be persuaded to give up a nuclear programme it has stubbornly built over the decades, often in secrecy and despite intense sanctions, global condemnation and widespread suffering among its people. "The haters, they say, 'Oh, you're giving him a meeting, '" Trump said. He credits his administration's "maximum pressure" campaign with getting Kim to the table.
"North Korea has previously confirmed to us its willingness to denuclearise and we are eager to see if those words prove honest", he said.
"The art of the deal is not just a title", he said, "it's a way at looking at life".
It's not just the logistics of Kim's trip that are unclear. -North Korea summit in Singapore.
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. He was accompanied by his sister Kim Yo Jong and Foreign Minister Ri Yong Ho.
USA and North Korean officials huddled throughout Monday at the Ritz-Carlton hotel ahead of the sit-down aimed at resolving a standoff over Pyongyang's nuclear arsenal. That would avoid the prospect of Kim winning sanctions relief for gradual progress while remaining a nuclear power.
The clearest benchmarks about what the U.S.is seeking from the summit, however, have come from Pompeo rather than Trump. "We're not going to go in and sign something on June 12, and we never were". "It's what happens after the agreement that really is the big point".
