A new round of U.S.-North Korea nuclear negotiations are set to begin in a few weeks following the Demilitarized Zone (DMZ) meeting between U.S. President Donald Trump and North Korean leader Kim Jong-un.

Washington is widely expected to let Secretary of State Mike Pompeo manage the entire strategy for better deliverables. U.S. Special Representative for North Korea Stephen Biegun is expected to back him up. Biegun is said to have been closely involved in fixing all the specifics of last week's Trump-Kim meeting.

There is a noticeable difference, however, in the line-up of North Korean negotiators.
