North Korean leader Kim Jong Un has called for a second summit with President Donald Trump and wants Secretary of State Mike Pompeo to return to Pyongyang for further talks toward denuclearization, South Korea President Moon Jae-in said Thursday.

"Chairman Kim expressed his wish to finish complete denuclearization at an early date and focus on economic development," Moon said after completing a three-day summit in the North Korean capital city.

Moon said Kim expressed a willingness to accelerate denuclearization of his country in exchange for security guarantees from the United States.

Trump on Wednesday tweeted that “North Korea recommits to denuclearization – we’ve come a long way.” Trump did not immediately respond to Kim's request for a second summit.

Moon said he and Kim discussed other issues not included in a joint declaration the two issued Wednesday. Moon said he would share details with Trump next week when the two meet in New York, where Moon will attend the U.N. General Assembly.

Moon also said he will stress to Trump the desire of both Koreas to formally declare an end to the Korean War by year's end. The war essentially ended in 1953 under terms of a cease-fire. At issue, however, is more than 25,000 U.S. troops stationed in South Korea and massive joint military operations those troops routinely conduct with South Korean forces.

The Korean leaders, after completing their third summit Wednesday, issued the joint declaration in which North Korea agreed to dismantle some nuclear facilities. The two nations also agreed on several issues aimed at reducing tensions and to pitch a joint bid to host the 2032 Summer Olympics.

While in Pyongyang, Moon also made an impassioned speech for unification.

"We had lived together for 5,000 years and have lived separately for only 70 years," he told a crowd of more than 100,000 in Pyongyang's May Day Stadium. "I urge all of you to end those hostilities and take a big step toward reunification."
