To further the September 2018 inter-Korean Comprehensive Military Agreement, UN Command, Republic of Korea Armed Forces, and North Korean People's Army officials met in a series of negotiations to deliberate the demilitarization of the Joint Security Area. The first two meetings in October led to Demining activities within the JSA, de-arming of personnel, and sealing off of Guard Posts. On November 6, 2018, UNC conducted a third round of negotiations with the South Korean military and North Korean People's Army on "Rules of Interaction" which would underwrite a Joint Security Area where both sides of the Military Demarcation Line—the de facto border—would be open to personnel. For undisclosed reasons, the North Korean side refused to meet to finalize these rules and the next step for realizing a demilitarized Joint Security Area.
