Kim Jong Un has agreed to hold a second summit with Donald Trump as soon as possible, Seoul officials said on Sunday, after US Secretary of State Mike Pompeo held “productive” denuclearization talks with the North Korean leader in Pyongyang.

Pompeo met with Kim on Sunday morning for around two hours of talks followed by a lunch in the North Korean capital, AFP reported.

Pompeo said “he agreed with Chairman Kim to hold the second US-North Korea summit at the earliest date possible,” South Korea’s presidential office said in a statement. However, no specific time or location has yet been agreed.
