The Joint Declaration of the Denuclearization of the Korean Peninsula was an agreed action item between South Korea and North Korea signed on January 20, 1992. The declaration was issued February 19.
The declaration read in part as follows:
At the same time, the Agreement on Reconciliation, Non-aggression and Exchanges and Cooperation between the South and the North (also known as the "South-North Basic Agreement") was made, covering the areas of: South-North Reconciliation South-North Non-Aggression South-North Exchanges And Cooperation
The joint Nuclear Control Commission specified by the agreement was created, and held 13 meetings in 1992 and 1993, but it did not come to any agreements. The last meeting was held in April 1993. So consequent to clause 6, the declaration never entered into force.
