US Secretary of State Mike Pompeo headed to Pyongyang for new talks with Kim Jong Un on denuclearization and a second US-North Korean summit.

Pompeo departed from Tokyo, where he spent the first leg of a tour that will include stops in Pyongyang, South Korea and China.

The trip will be Pompeo’s fourth to Pyongyang, as the contours of a possibly historic US-North Korea deal take shape.

Mike Pompeo said his aim is to “develop sufficient trust” between Washington and Pyongyang to inch towards peace.

However, he played down expectations for a major breakthrough.
