Trump became the first sitting U.S. president to cross the 1953 armistice line separating North and South Korea, then joined Kim side-by-side for a roughly 50-minute meeting in the heavily-fortified demilitarized zone. It was their third since Trump took office, but none have yet yielded a nuclear deal.
Trump and Kim shook hands across a concrete slab forming the line between to the two nations at the DMZ, according to a reporter traveling with the president.
"Good to see again," Kim said, according to a translator. He added he would have "never expected" Trump "at this place."
Shortly after, Trump said "Good progress, good progress," as he and Kim crossed back into South Korea. "Stepping across that line was a great honor," Trump said, adding that he would invite Kim to visit the White House.
"I think it's historic, it's a great day for the world."
