PANMUNJOM: Donald Trump stepped onto North Korean soil in a historic first on Sunday as he met Pyongyang`s leader Kim Jong Un in a moment of high diplomatic drama on the world`s last Cold War frontier.

Moments after becoming the only sitting US president to set foot inside North Korea, Trump brought Kim back over the dividing line for a meeting where they agreed to start working-level t alks on Pyongy ang`s nuclear weapons.

Trump also said he had invited the young leader to the White House `anytime he wants to do it` `It was an honour that you asked me to step over that line, and I was proud to step over the line,` he told Kim.

As they sat down for discussions, the North Korean leader said their `handshake of peace` in a location that was `the symbol of the division of north and south` showed that `we are willing to put the past behind us`.

The impromptu meeting in the DMZ after Trump issued an invitation on Twitter on saturday came with negotiations between Pyongyangand Washington at a deadlock.

Their first summit took place in a blaze of publicity in Singapore last year but produced only a vaguely worded pledge about denuclearisation. A second meeting in Vietnam in February intended to put fiesh on those bones broke up without agreement.

Contact between the two sides has sincebeenminimal-withPyongyang issuing frequent criticisms of the US position but the two leaders exchanged a series of letters before Trump issued his offer to meet at the DMZ.

Trump`s entry onto North Korean soil which he said was uncertain until the last moment is an extraordinary sequel to the scene at Kim`s first summit with Moon Jae-in last year, when the young leader invited the South Korean president to walk over the Military Demarcation Line, as the border is officially known.

A Kim trip to Washington would be even more spectacular, although Trump said the visit would happen `at the right time` Moon seized on last year`s Winter Olympics to broker the process between Pyongyang and Washington, after tensions soared in 2017 as the North carried out multiple missile launches and its biggest nuclear test to date, while Trump and Kim traded mutual insults and threats of war.The significance of the meeting in the no-man`s-land splitting the peninsula where the two sides and their allies fought each other to a standstill in the 1950-53 Korean War was `obvious`, said Stimson Centre Asia analyst David Kim.

`It`s historic for Trump to be the first US president to enter North Korea soil, historic for Moon to meet, albeit briefly, with both leaders.

The meeting had the `potential to kick-start stalled negotiations`, he said, but added that working-level discussions would be crucial.

`What we need is substance, not theatrics.

The Hanoi summit foundered on disagreements over what the North which has carried out six nuclear tests and developed missiles capable of reaching the entire US mainland would be willing to give up in exchange for relief from sanctions that have hobbled its economy.

The DMZ has been a regular stop for US presidents visiting the South, a security ally although Trump`s helicopter was forced to turn bacl( by fog in 2017 while Panmunjom saw the first two summits between Moon and Kim last year.

`This was a great day,` the US president said before flying out on Air Force One.

`This was a very legendary, very historic day.`-AFP
