Substantial progress was made Monday in Pyongyang, where a South Korean delegation met with North Korean leader Kim Jong Un on day one of a major two-day discussion on continuing to improve diplomatic relations.
North Korea's state media even reported that the discussion included an agreement reached between the two sides, though exact details on what was agreed upon were not made public. Among the things agreed to, however, was to continue to work toward a summit in which Kim and South Korea's President Moon Jae-in would meet.
The delegation in Pyongyang now, and the North Korean delegation to South Korea's Winter Olympics weeks ago were both among the highest profile diplomacy between the two Koreas in history. A direct summit, however, would be truly unprecedented.
