US President, Donald Trump has said he was not able to arrange a meeting with North Korean leader Kim Jong Un during his visit to the South, ending fierce speculation over a possible summit.

Trump had said he would “love to meet” Kim during his Asia trip, which would have been their first meeting since the US leader’s previous term in the White House. North Korea has not responded publicly to the invitation.

The duo’s last and impromptu meeting took place at Panmunjom, in the DMZ which separates the two Koreas. It was hastily arranged after Trump extended an invitation to Kim on Twitter a day prior.

That event saw the two leaders shake hands over the concrete slabs dividing North and South before Trump walked a few paces into Pyongyang’s territory — becoming the first US president ever to set foot on North Korean soil.

But talks collapsed over just how much of its nuclear arsenal the North was willing to give up and what Pyongyang would get in return.
