The US is likely to offer North Korea "unique" security guarantees to persuade it to give up its nuclear arsenal, secretary of state Mike Pompeo said Monday, on the eve of a historic summit in Singapore.
He continued: "But in the end, that doesn't matter".
"Any denuclearization must fully reject nuclear weapons and use existing worldwide frameworks to ensure long-term success that would withstand any future changes".
In the run-up to Tuesday's historic face-to-face with Kim, Trump has appeared unconcerned about the implications of feting an authoritarian leader suspected of ordering the public assassination of his half brother with a nerve agent, executing his uncle by firing squad and presiding over a notorious gulag estimated to hold 80,000 to 120,000 political prisoners. They also say by winning the prestige of a meeting with the world's most powerful leader, Mr Kim has already gained a victory. Trump is pushing for complete, verifiable, irreversible denuclearisation - considered the gold standard among arms control experts.
Joint armed forces of from the Chinese police and the People's Liberation Army have enforced tight security in the border area of Dandong in northeastern China's Liaoning province, that lies across from North Pyongan province, the source told RFA's Korean Service.
In the lead-up to the summit, USA and North Korean officials were convening contentious final-hour negotiations in a Ritz Carlton hotel here in a bid to narrow gaps on key aspects of the meeting. A final working lunch with Kim is planned to conclude the summit.
For decades, North Korea has been a pariah state, and now its latest hereditary leader is being treated as a world statesman. Trump said. "We will be fine!"
The failure of the six-party talks demonstrates the key problem in negotiating with North Korea: even after getting everything it wanted out of the talks, the country failed to hold up its end of the bargain and resumed a hostile posture and its pursuit of nuclear weapons.
Trump has also said he'd consider inviting Kim to Washington for a second round of talks.
He smiled at citizens who cheered for him.
The eccentric former reality television star is one of the few westerners to have spent time with Kim during multiple visits to Pyongyang and the two struck up an unlikely friendship over their shared love of basketball. "If they don't denuclearise, that will not be acceptable".
A sit-down with the U.S. president is something North Korea has long pushed for.
Mr Trump famously vowed to unleash "fire and fury" if Pyongyang kept threatening the US. But Trump's off-the-cuff negotiating style - and his growing disregard for many of Washington's closest allies - makes it hard to predict what any such a deal might include. Kim then called Trump a "mentally deranged United States dotard" and a "frightened dog".
That's a massive shift in Kim's public persona, and it might show one of the reasons both Trump and Kim were eager for this meeting to take place: Regardless of what actually happens, worldwide summits can be a pretty big PR boost.
"We hardly ever talk politics", Rodman said.
Trump and his advisers have said the USA would accept nothing less than full denuclearization before sanctions against the North are lifted, and before North Korea can be fully welcomed into the fold of the broader diplomatic community. The topics discussed were not immediately disclosed, but Trump said he approved of the progress made.
It was a far cry from a year ago when Trump threatened North Korea with "fire and fury" and mocked Kim as "little rocket man", and Kim denounced the USA president as the "mentally deranged US dotard".
