WASHINGTON – US President Donald Trump said here on Tuesday in his State of the Union address that he will meet with Kim Jong-un, the leader of Democratic People's Republic of Korea (DPRK), on Feb 27-28 in Vietnam.

Much work remains to be done, but my relationship with Kim Jong-un is a good one.

"Much work remains to be done, but my relationship with Kim Jong-un is a good one. Chairman Kim and I will meet again on February 27 and 28 in Vietnam," he added.

US State Department said earlier on Monday that Stephen Biegun, US special representative for DPRK-related issues, will travel to Pyongyang later on Wednesday for meeting with his DPRK counterpart, Kim Hyok Chol, to lay the groundwork for the second Trump-Kim summit and to "advance further progress on the commitments the President and Chairman Kim made in Singapore: complete denuclearization, transforming US-DPRK relations, and building a lasting peace on the Korean Peninsula."
