South Korea's defense ministry on Friday formally proposed military talks with North Korea, asking the two sides to confirm exactly where their land border runs, restore severed military communication lines and prevent accidental clashes along the most heavily fortified frontier in the world. The offer, announced in Seoul on October 23, follows a land mine explosion inside the Demilitarized Zone (DMZ) last month that injured three South Korean soldiers, two of them seriously.
Deputy Defense Minister Kim Hong-cheol delivered the proposal at a briefing in Seoul, saying the two Koreas still hold different understandings of where the Military Demarcation Line (MDL), the line at the center of the DMZ, actually lies in certain areas. Kim said the date and venue could be discussed through Panmunjom, the truce village, and that a three-way meeting with the United Nations Command, which administers the armistice, would also be possible.
"We formally propose holding talks between the military authorities of South and North Korea to jointly verify the precise location of the land-based MDL, discuss restoring military communication lines and explore ways to prevent accidental clashes in border areas."
The immediate trigger was the September 21 blast. South Korean troops were clearing a path for a joint UN Command investigation into the North's border-hardening work when the mine exploded. South Korea's military investigation concluded that the blast was caused by North Korean mines planted south of the MDL. Pyongyang has rejected those findings, denied responsibility for the explosion and accused Seoul of fabricating its investigation results; North Korean officials have also vowed to take military action along the border if provoked.
Seoul says the underlying problem is that the line itself is fading. Of the 1,292 marker posts installed along the MDL under the 1953 Armistice Agreement, only about 200 remain identifiable today. South Korea reads the line from U.S. National Geospatial-Intelligence Agency mapping, the UN Command works from its own 2016 coordinates, and North Korea is believed to rely on its surviving physical markers — three different maps for one line. In recent years North Korean troops have been building tactical roads and fences and laying mines near the line, crossing it in the process; South Korea's military estimates the North has planted roughly 960,000 land mines in the DMZ area since 2024. Seoul says the confusion has already driven up its warning broadcasts and warning shots.
"Without special measures, troops on both sides of the border will continue operating based on where they believe that the line lies, increasing the risk of accidental clashes," Kim said, warning that "it is difficult to predict what other incidents could occur if this situation is allowed to continue." He added: "We hope for a positive response from the North."
Pyongyang's public position this week pointed the other way. In an English-language statement issued through the state-run Korean Central News Agency on Wednesday, Kim Yo-jong, sister of North Korean leader Kim Jong-un, stressed that "the border should be a permanent line never to be crossed." Pak Jong-chon, an adviser to North Korea's defense ministry, said in a separate KCNA statement: "Our army knows where our borderline is better than any others, and we are doing what we should do in our territory." Seoul informed the UN Command before the announcement; the Command reaffirmed its commitment to upholding the armistice and "reducing the risk of miscalculation and unintended escalation," but declined to say whether it had passed the offer on. South Korea made a similar proposal last November; North Korea never responded.
Both governments state their positions plainly: Seoul says a disputed, poorly marked line is now injuring soldiers and inviting a clash neither side can fully control, while Pyongyang says it knows where its border is, rejects Seoul's account of the mine blast, and is fortifying its own territory. Whether the two militaries talk is now, as it was last November, Pyongyang's decision to make.
