"Makes me feel very good, I love our farmers", Trump said, adding that the deal would double the cars per manufacturer that can enter the South Korean market while meeting USA safety standards.
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.
Trump said the deal was "fair and reciprocal", and will both reduce the trade deficit and expand opportunities to export American products to South Korea, including automobiles, medicine and agricultural products.
The leaders signed an update to an existing U.S.
Trump praised Kim as "very open" and "terrific", despite the glacial pace of progress toward denuclearization on the Korean Peninsula.
President Donald Trump raised hopes at the United Nations on Monday that a second meeting with North Korea's Kim Jong Un could occur "quite soon", striking a conciliatory tone one year after he used his debut at the U.N.to deride the autocrat as "Little Rocket Man" and threaten to "totally destroy North Korea".
"We're bringing the two senior leaders, the individuals who can actually make the decisions that will move this process forward, bring them together so we can continue to make progress towards what the UN Security Council has demanded and what Chairman Kim has promised he would do".
Noting that many fear a formal end to the 1950-53 war may weaken the reason for the United States to continue maintaining tens of thousands of U.S. troops in South Korea, Moon said it would only be a political declaration that has nothing to do with USA forces in Korea, and that the North Korean leader shared such a view. While Trump is not seeking a meeting with Rouhani, he is open to talking with the Iranian leader if Rouhani requests one, administration officials said.
Speaking earlier, at United Nations headquarters in NY, he said that Secretary of State Mike Pompeo would arrange the next summit "in the immediate future".
Moon's trip to NY is also aimed at explaining the outcome of his third bilateral summit with Kim to the world.
Nikki Haley, the USA ambassador to the United Nations, told reporters in a preview of Trump's visit, that the president's focus "will be very much on the United States", its role and the relations it wants to build. But no American company sells much more than 10,000 cars a year in South Korea.
Trump will be joined by other populist leaders at the 73rd General Assembly, including Poland's President Andrej Duda and Italy's Prime Minister Giuseppe Conte along with the foreign ministers of Hungary and Austria. He's calling for global action to address the illegal movement and abuse of drugs.
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.
Trump was elected promising to address US opioid addiction.
Still, Kim remains committed to denuclearization, according to Moon, who said he would debrief Trump on his own meetings with the North Korean dictator just last week.
