In his 41-minute speech at the General Assembly in 2017, the U.S. president made clear he wanted to turn the clock back on the last half-century's growth of global rules and institutions, to return to the primacy of the nation-state.
He said the new trade agreement, which still needs approval by South Korea's parliament, was a sign of the strong partnership between the US and South Korea.
South Korean President Moon Jae-in isn't letting that happen again.
Moon says companies from both countries will be able to do business under more stable conditions.
While relations with Kim have improved dramatically, leaders attending the annual assembly will hear how another of Trump's adversaries, Iran's Hassan Rouhani, remains a top target of the American president's ire.
No decision had yet been taken as to the venue, he said.
Bolton said the United States was seeking to ramp up pressure on Iran but not to overthrow the regime - an idea he supported before taking his job and reiterated recently by former NY mayor Rudy Giuliani, who is Trump's personal lawyer.
As he started the sequel to his stormy United Nations debut, Trump confronted anew the dangers posed by North Korea's nuclear threat, though its shadow may appear somewhat less ominous than a year ago.
The Trump administration is turning to allies in Asia and Europe for trade deals as US relations with China deteriorate and the two world's largest economies exchange tit-for-tat tariffs that risk damaging global commerce.
If there is a through line to the still-evolving Trump doctrine on foreign policy, it is that the president will not subordinate American interests on the world stage, whether for economic, military or political gain. USA ambassador to the United Nations Nikki Haley said last week the two had agreed to meet but said the meeting could take place later.
"That was a risky time".
Trump's address to the General Assembly comes Tuesday, and on Wednesday he will for the first time chair the Security Council, with the stated topic of non-proliferation of nuclear, chemical and biological weapons. Moon is expected to convey to Trump a personal message from Kim delivered at their inter-Korean talks last week. "This is one year later, a much different time".
Kicking off his meetings, Trump addressed "the world drug problem and a big problem it is" at an event that saw 130 countries pledge in general terms to step up action to fight the illegal drug trade and combat addiction.
Twelve months after Trump stood at the rostrum of the U.N. General Assembly and derided North Korea's Kim Jong Un as "Rocket Man", the push to denuclearize the Korean Peninsula is a work in progress, although fears of war have given way to dreams of rapprochement.
Just a year ago, the USA and North Korea were publicly speaking of a nuclear confrontation but Mr Trump had historic first talks with Mr Kim in June.
