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.
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. "Workers in South Korea and America will find new customers and new opportunities to expand and grow", Trump said.
"It looks like we´ll have a second summit quite soon", Trump told reporters at the United Nations.
The president said he thinks American farmers "are going to be extremely happy", and be sending a lot more farm products to South Korea. In both venues, USA officials say, he is expected to offer a contrast between the path of negotiation chosen by North Korea and that of Iran.
The US president similarly described the trade deal with Seoul as a breakthrough and completely unlike an earlier deal, known as Korus, negotiated by the Obama administration. The deal with South Korea is more complicated because of North Korea, which is in the midst of negotiations with the USA and South Korea over the dismantling of its nuclear program.
Long critical of the United Nations, Trump delivered a warning shot ahead of his arrival by declaring that the world body had "not lived up to" its potential.
"We've imposed very stringent sanctions on Iran, more are coming, and what we expect from Iran is massive changes in their behavior", he said. Trump said he will meet with Rosenstein on Thursday upon his return to Washington.
Trump is set to address the U.N. General Assembly Tuesday morning and will chair a meeting of the Security Council Wednesday on counter-proliferation. "This is one year later, a very different time".
But while some world leaders are still reeling from Trump's deference to Putin in their summer Helsinki summit, there will not be an encore in New York: The Russian president is not expected to attend the proceedings.
"A lot of progress" was being made, he said, speaking alongside South Korean President Moon Jae-in in NY.
"Today we commit to fighting the drug epidemic together", he added.
As he begins the sequel to his stormy United Nations debut, President Donald Trump will again confront the dangers posed by North Korea's nuclear threat, though its shadow may appear somewhat less ominous than a year ago. "But under no definition of reverse could I say that North Korea couldn't make more or better nuclear weapons than it does now".
The president, whose bellicose denunciations of Pyongyang have largely given way to hopeful notes, plans to sit down with South Korean President Moon Jae-in, who comes bearing a personal message to Trump from North Korea's Kim after their inter-Korean talks last week.
