South Korea and North Korea have held a total of 667 inter-Korean meetings over the past 50 years, underscoring the multiple levels at which dialogue is possible with Pyongyang, according to a new report published by Seoul’s Ministry of Unification (MOU) on Monday.

While summit meetings between the leaders of the two Koreas are the most well-known and publicized, they account for a tiny fraction of the hundreds of face-to-face meetings between the two Koreas since Aug. 20, 1971, according to the ministry.
