The history of the Military Demarcation Line (MDL) between the two Koreas begins with the armistice that ended open hostilities in 1953. The United Nations command, created after a series of negotiations, has been in charge of monitoring this border since that date, according to South Korea’s Yonhap News Agency. In light of the South Korean army’s recent initiatives to review the border and prevent incidents with North Korea, this US-led international organization reaffirmed its authority over the area, rejected unilateral changes and stressed the need for any dialogue to take place under its formal supervision.
According to Yonhap, the United Nations Command issued a statement saying, “The United Nations Command reaffirms its commitment to complying with the ceasefire agreement, including the MDL, and supporting measures that prevent escalation and promote stability in the Demilitarized Zone (DMZ).” This message appeared against the backdrop of growing border tensions and was in response to the request of the South Korean General Staff, which recently reminded its troops of the priority of adhering to the limits agreed in the MDL. According to government sources who told the Yonhap Agency, they also suggested using the map drawn up by Seoul and the line connecting the United Nations Command markings if there were any doubts about the exact demarcation.
As the above-mentioned agency reported, the powers of the United Nations Command also left no room for ambiguity regarding the management of the DMZ. “Since 1953, the United Nations Command has successfully managed the DMZ, a role that is critical to maintaining stability, especially during times of intense inter-Korean tensions,” the statement said. This body’s responsibilities are not limited to passive surveillance: it controls the South Korean side of the Common Security Space, a space where representatives of Seoul and Pyongyang can meet for negotiations and which is the only direct point of contact at the border level.
As Yonhap detailed, in mid-November the South Korean government formally proposed to the North that military talks be held to demarcate the MDL and thus reduce the possibility of armed confrontations in the shared area. This offer came at a time when North Korean maneuvers and work near the border increased unrest in the region and reinforced the need to maintain channels of dialogue that ease tensions.
At the time of original publication, the Pyongyang regime had not given a positive response to South Korean President Lee Jae Myung’s calls for resuming dialogue and finding diplomatic solutions to the protracted conflict. According to Yonhap, the last round of bilateral military talks between the two countries took place in 2018, although both states are still technically in a state of war as there is only a ceasefire and no final peace treaty.
The United Nations Command, established during the Korean War as a multinational force under American leadership, has retained its supremacy in the region as a guarantor of the ceasefire. In his statement, he insisted that any review of the design or action related to the military border must be carried out within the legal framework and protocols established in 1953 to ensure that any discussion takes place “under the auspices” of this body and not by the unilateral will of one of the parties.
In addition, the reaffirmation of the authority of the United Nations Command had an impact on the current situation, where deployments, military exercises and infrastructure work near borders can increase volatility. The control structure over the DMZ and international participation, mainly from America, are portrayed as a containment factor at times when incidents and disagreements can lead to escalations that are difficult to control, according to information released by Yonhap.
The parties involved continue to await a response from the North Korean leadership and the possible opening of new rounds of contacts, while surveillance at the shared border continues to be carried out under strict observation and application of multilaterally agreed protocols. The DMZ, a dividing line and eventual contact area, will continue to be managed according to criteria established more than seven decades ago, the United Nations command emphasizes in the text published by the Yonhap Agency.
