What little is known about the man North Korean leader Kim Jong Un has tapped to prepare his summit with U.S. President Donald Trump suggests he¡¯s more familiar with defending Pyongyang¡¯s nuclear arsenal than giving it up.

Kim Hyok Chol, a career diplomat from an elite North Korean family, made his international debut just a few weeks ago as Pyongyang¡¯s new point man for nuclear negotiations. In the run-up to the Feb. 27-28 summit, he has been in talks with U.S. counterpart Stephen Biegun to lay the groundwork for the meeting, taking diplomats by surprise.

To those who know him, Kim Hyok Chol is a skilled rhetorician who has played a crucial role in crafting the joint statement signed by the North Korean leader Kim and South Korean President Moon Jae-in at their latest summit last year. He also has a connection with Kim Jong Un, serving on the State Affairs Commission, the most powerful governing group chaired by the North Korean leader.
