The United States said it is ready to resume talks with North Korea after Pyongyang pledged Wednesday to dismantle its key missile facilities and suggested it will close its main Nyongbyon nuclear complex if Washington takes unspecified actions.

U.S. Secretary of State Mike Pompeo said he has invited North Korean Foreign Minister Ri Yong Ho to meet him in New York next week, with the aim of completing its denuclearization by January 2021, after a Pyongyang summit between the leaders of the two Koreas.

The United States appeared eager to seize on commitments by North Korean leader Kim Jong Un at his talks with South Korean President Moon Jae-in even as critics said the steps did little to put Pyongyang on a course for irreversible denuclearization.
