BEIJING — North Korean leader Kim Jong Un has reportedly told the leader of his only major ally, China, that he is committed to setting up a second summit with President Trump to “achieve results” on the nuclear standoff on the Korean Peninsula.

The comments, contained in reports Thursday from Chinese and North Korean state media, came after Kim left Beijing on his special armored train for Pyongyang after a two-day visit to the Chinese capital.

Kim’s trip to China – his fourth in the past 10 months – is believed to be an effort to coordinate with Beijing ahead of a possible second summit with Trump. It comes after U.S. and North Korean officials are thought to have met in Vietnam to discuss the site of the summit.

Kim met with Chinese President Xi Jinping during his trip, Chinese and North Korea state media reported Thursday. It wasn’t clear from the reports if Kim was in back in the North, but his train presumably would arrive sometime Thursday.
