South Korean President Moon Jae-in has prioritized mending ties with North Korea. His high-stakes diplomacy is playing out on the sidelines of a US effort to get Pyongyang to give up its nuclear weapons.

Trump made history when stepped across a low concrete marker accompanied by North Korean leader Kim Jong-un and walked a few steps into the North. The two leaders agreed to have their negotiators resume an effort to reach what has so far been an elusive nuclear deal. US President Donald J.
