The two Koreas recently had a chat at Panmunjun, the truce village within the Demilitarized Zone. They reached an agreement. To talk some more.

That's the way it usually is. When there's a specific issue that must be resolved, real results sometimes are reached. But promises of future talks usually fall short. For instance, two years ago the two Koreas agreed to hold top level discussions: the North pulled out the day before.

Will this time be any different? The two sides chatted on Dec. 11, but failed to schedule any new sessions.
