North Korean leader Kim Jong Un joked about his image in international media while serving South Korean officials local spirits and cold noodles during their unprecedented visit to Pyongyang this past week, two South Korean government sources said.

During the meeting, Kim committed to giving up his nuclear weapons and told the South Korea officials he would like to meet U.S. President Donald Trump, delegation leader Chung Eui-yong told reporters at the White House on Thursday — a potentially dramatic breakthrough in nuclear tensions with Pyongyang.

During their meetings, Kim made light-hearted remarks about how he is viewed outside North Korea in international media and elsewhere, one Blue House official said. The officials who spoke asked to remain unnamed due to the sensitivity of the issue.
