Following the meeting, Pompeo will fly to Seoul for a meeting with President Moon Jae-in and Foreign Minister Kang Kyung-wha later Sunday and brief them on the results of his trip to the North.

On Monday, he will depart for Beijing for further talks with Chinese officials.

His visit to the North, his fourth, comes as the US. and the North are trying find a breakthrough in the stalled denuclearization negotiations.

The US. has insisted that the North must declare its nuclear arsenal before any peace process moves forward, but the North has sought an initial end-of-war declaration from the US.

Progress from Pompeo's Pyongyang trip would help revive denuclearization talks and set details for the planned second summit between Kim and US. President Donald Trump.

"Each side has to develop sufficient trust so they can take the actions necessary to get to the end, and then we're also going to set up the next summit," Pompeo said on a stop in Anchorage, Alaska, before arriving Japan.

"So we hope to at least -- I doubt we'll get it nailed, but begin to develop options for both location and timing that Chairman Kim will meet with the president again. Maybe we'll get further than that," he said. (Yonhap)
