No Response to North Korean Mine Explosion... Greater Risks Ahead [Yang Nakkyu's Defence Club]

Military Authorities' Only Response Is "North Korean Mine Clearance Operation"
More Landmines South of the MDL Raise Concerns Over Additional Incidents

Although the South Korean military has identified North Korea as the main perpetrator in the recent explosion incident in the western front area of the Demilitarized Zone (DMZ), it has not proposed any direct countermeasures. There are growing concerns of additional accidents, as North Korea continues to deny the Military Demarcation Line (MDL)—a boundary recognized by the United Nations Command Military Armistice Commission and North Korea itself—and is increasing the placement of landmines south of the line.

Kim Sungyun, Director of Intelligence Analysis at the Joint Chiefs of Staff (Brigadier General, Army), stated during a final investigation results briefing on the 5th, "We have identified several suspected areas where North Korean troops have planted landmines south of the MDL," and added, "The width of these incursions varies by region, averaging around 20 meters beyond the MDL." No specific countermeasures were presented. The only declared action was that if North Korea does not voluntarily remove the mines, South Korea will carry out mine clearance operations for North Korean landmines found south of the MDL.

The underlying issue is that South and North Korea use different standards for defining the MDL itself. In 1953, immediately after the signing of the armistice agreement, both Koreas installed 1,292 markers under the supervision of the United Nations Command Military Armistice Commission to represent this virtual line. The South Korean military currently relies on the MDL as depicted in the 2004 U.S. National Geospatial-Intelligence Agency’s military maps, while North Korea uses a different approach—applying a virtual boundary in areas where the markers are hard to identify. As a result, North Korea has crossed approximately 20 meters south of the MDL and is planting landmines in these areas. Since declaring South Korea an "enemy state" in late 2023, North Korea began reinforcing its borders in April 2024 by planting mines and installing barbed wire fences.

Going forward, North Korea is expected to complete the clearing of vegetation to create a no-man’s land as part of its efforts to fortify the entire 250 km stretch of the MDL as a border. Currently, progress on installing fences, laying minefields, and constructing tactical roads is at approximately 40% to 60%, with completion projected within the next two years. This indicates that both MDL incursions and the planting of landmines will likely increase in the future. In 2024 alone, North Korea crossed the MDL over 50 times, compared to 9 times in 2024 and 17 times last year.

Shin Jongwoo, Secretary-General of the Korea Defense and Security Forum, commented, "North Korea is violating the MDL, installing fences, and conducting daily patrols. If our military proceeds with mine clearance, the likelihood of direct encounters with North Korean troops will rise, increasing the risk of military clashes."
