Kim and Xi assessed the historic meeting Kim had with US President Donald Trump in Singapore last week and exchanged opinions on ways to resolve the issue of denuclearisation, Korean Central News Agency (KCNA) said.

The North Korean leader also promised during a meeting with Xi in Beijing to cooperate with Chinese officials to secure “true peace” in the process of “opening a new future” on the Korean peninsula, it said.

Kim’s two-day visit to Beijing will end later on Wednesday, according to state media from China and North Korea. It follows his Singapore summit, where Kim and Trump reaffirmed a commitment to work towards complete denuclearisation of the Korean peninsula.

Trump surprised officials in South Korea and the United States after that meeting by saying he would end “provocative” joint US-South Korean military exercises.

The United States and South Korea said on Tuesday they had agreed to suspend a joint military exercise scheduled for August, although decisions regarding subsequent drills have not yet been made.

Kim is on his third visit to China this year. Xi offered high praise to the North Korean leader on Tuesday for the “positive outcome” of last week’s summit.

KCNA also reported that Xi said relations between China and North Korea had entered a new level of development since Kim’s first visit in March and that the agreements made between the two leaders were being carried out “one-by-one”.

Kim also told Xi he was willing to bolster the bilateral friendship and cooperation, it said.

It was expected that Kim would visit Beijing to brief Xi on his summit with Trump, which included Pyongyang agreeing to hand over the remains of troops missing from the 1950-53 Korean War.

Two U.S. officials told Reuters on Tuesday North Korea could start that process within the next few days.
