UNC and Defense Ministry in Continued Dispute [Yang Nakkyu's Defence Club]

Disagreement Over North Korea's Installation of Fences Near the MDL
UNC: "No Issue" vs Defense Ministry: "Violation of the Agreement"

The United Nations Command (UNC) and South Korea's Ministry of National Defense have clashed once again. The UNC has directly countered the South Korean Defense Ministry over the issue of whether North Korea's recent border demarcation work along the Military Demarcation Line (MDL) constitutes a violation of the armistice agreement.

It has been reported that North Korean troops have crossed the Military Demarcation Line (MDL) into South Korean territory five times this year alone.

On June 24, the UNC posted an explanatory statement on its website, effectively refuting the South Korean Ministry of National Defense's position that the installation of fences near the MDL by North Korean troops is a clear violation of the armistice agreement.

In a post titled "UNC Explanation: Armistice Implementation in the Demilitarized Zone (DMZ) and Recent North Korean Activities," the UNC emphasized that it maintains the position that recent North Korean construction activities—including the installation of fences and road maintenance—are taking place north of the MDL, and as long as they do not involve the introduction of heavy weapons, they do not constitute a violation of the 1953 armistice agreement.

Specifically regarding North Korea’s installation of fences and road repairs, the UNC stated, "If these activities are conducted north of the MDL, they are permissible. Fences are facilities for defensive and separation purposes," determining that these are not violations of the armistice agreement. The UNC also clarified that the laying of mines is not a violation either, stating, "It is permissible for the North to lay mines in its own territory for defensive purposes."

The UNC explained that in most areas, North Korean construction activities are being carried out within a maximum distance of 100 meters from the MDL, as established by the 1953 armistice agreement. It stated that there is no evidence of MDL crossings, and monitoring has found no evidence that North Korea has brought heavy weapons or drones into the DMZ. Additionally, the UNC noted that South Korea is currently undertaking more than 36 projects related to road construction, fencing, and vegetation clearing in the southern DMZ. The UNC stressed that these activities also do not violate the armistice agreement and that "the UNC applies the same standards to both sides." By listing the DMZ activities of both North and South Korea, it is implied that similar actions are being taken by both sides, and that North Korea cannot be singled out.

The UNC stated, "In recent operations, North Korean troops have used established communication mechanisms with the UNC to prevent misjudgments," and specifically disclosed details of past communications with the North. According to the UNC, North Korea notified in October 2024 of its intention to block transportation corridors (roads and railways connecting with the South), and in the summer of the previous year, it notified the UNC of plans to begin fence construction and road repair work.

The UNC further revealed that it actively issued warnings to North Korea regarding activities near the MDL, prompting North Korean troops to adjust their posture and withdraw northward to prevent accidental border crossings.

Meanwhile, South Korea's Ministry of National Defense has defined North Korea's border demarcation work—particularly the construction of fences just 80 to 90 meters from the MDL—as a "clear violation" of the armistice provisions that designate the DMZ as a buffer zone. The government has conveyed on several occasions its opinion that, since North Korea's border demarcation efforts could effectively neutralize the buffer zone and lead to the militarization of the DMZ, the UNC should play a role in on-site verification and related efforts.

Tensions between the UNC and the Ministry of National Defense have persisted. In November of last year, the Ministry of National Defense announced that it had "expressed its intent for talks with the North through the UNC" to hold inter-Korean discussions on determining the MDL. However, the UNC denied having conveyed such a position to the North. Regarding the UNC Commander’s jurisdiction over the DMZ as stipulated in the armistice agreement, the Ministry of National Defense argued that some areas should be separated and placed under South Korean military control, claiming "significant progress" was made at the South Korea-U.S. Integrated Defense Dialogue last month. The UNC, however, reiterated its existing position that "jurisdiction rests with the UNC Commander."
