SEOUL — North Korean leader Kim Jong Un publicly acknowledged for the first time the prospect of a “dialogue” with the U.S. and a planned summit meeting with South Korea’s president, breaking a weekslong silence that had raised questions about Pyongyang’s participation in the high-level meetings.

Kim, speaking at a meeting of the Politburo of the Workers’ Party of Korea on Monday, “made a profound analysis and appraisal of the orientation of the development of the north-south relations at present and the prospect of the DPRK-U.S. dialogue,” according to a state media report published Tuesday in Pyongyang.
