Donald Trump, on Tuesday, became the first United States president to set foot in North Korea on Sunday as he greeted Kim Jong Un, the country's leader, at the heavily fortified Demilitarized Zone.
President Donald Trump says he "was proud" to step over the demarcation line between North and South Korea, becoming the first US president to enter North Korea.
The North Korean leader Kim Jong Un responded that his "wonderful" relationship with US President Donald Trump would enable the two longtime enemies to get over obstructions, with their nuclear talks at a stalemate.
While many warn the latest summit risked normalizing friendly relations with a brutal dictator, South Korea's President Moon said the meeting was an important step toward building trust with North Korea.
The DMZ has been a regular stop for U.S. presidents visiting the South, a security ally - although Trump's helicopter was forced to turn back by fog in 2017 - while Panmunjom saw the first two summits between Moon and Kim past year.
Mr Trump said the meeting was "very historic" and hit out at his critics who have argued that nothing has emerged from his two summits with Mr Kim.
"It's a great day for the world and it's an honour for me to be here", Trump said. "A handshake means a lot", he added.
He described his relationship with North Korea's leader as a "great friendship".
He becomes the first serving American president to step into the country.
The meeting offer of Trump to Kim came hours after his special representative to North Korea on Friday Stephen Biegun told his South Korean counterpart, Lee Do-hoon, that the US was "ready to hold talks with North Korea to move their denuclearization negotiations forward in a simultaneous and parallel manner".
Trump later said he had invited Kim to the US.
April 13, 2019: Kim says he is open to another meeting with Trump, but sets the year's end as a deadline for Washington to offer mutually acceptable terms for an agreement to salvage the diplomacy.
Trump and Kim held an unprecedented summit in Singapore in June a year ago, agreeing to forge new relations and work towards denuclearisation of the Korean peninsula. Kim Jong-un also added, "It's a very courageous and determined act".
"I think there's a chance that Trump and Kim will meet at the DMZ on June 30 through the so-called NY channel", he said. "I'd like to pay tribute to the bold and creative approach taken by President Trump".
"It's just a step and probably a step in the right direction", said Trump.
"It will demonstrate that nuclear weapons turn a pariah into a force to negotiate with", she said.
"Peace and security on the Korean Peninsula will entirely depend on the U.S. future attitude, and the DPRK will gird itself for every possible situation", KCNA quoted Kim as saying in April.
Mr Trump briefly crossed the border into North Korea after greeting Mr Kim.
Trump's surprise trip to South Korea was announced on Friday while the president was in Japan for the G20 summit. The show of bravado and support for South Korea, one of America's closest military allies, has evolved over the years to include binoculars and bomber jackets.
