Tensions mount over DMZ mine blast as North Korea alludes to military response

Kim Yo-jong, the powerful sister of North Korean leader Kim Jong-un, dismissed a recent DMZ mine blast that moderately injured three South Korean soldiers as a “clear farce,” while warning that the incident could further escalate already strained inter-Korean relations and raise the prospect of military retaliation.

 As efforts to ease inter-Korean tensions become increasingly complicated, experts stress the need for Seoul to make a measured response while opening up channels of communication.

 In a statement published by the Korean Central News Agency on Wednesday, Kim slammed the findings of a South Korean military investigation that attributed the explosion to a North Korean land mine, labelling it a “conspiratorial farce” and “method of provocation.”

 Kim claimed that the III Corps’ 21st Infantry Division had been frequently provoking the North, which has pushed the North to take measures to increase tactical counterattack means.

 In response, Kang Hyeon-woo, the director of operations at South Korea’s Joint Chiefs of Staff, clarified on the same day that the incident had been caused by North Korean mines, and urged North Korea to immediately halt all activities — including fortifying the border — that aggravate tensions on the Korean Peninsula.

 He also demanded that the North apologize for the incident and take appropriate measures in response. 

 The UN Command, which can judge whether an act violated the Armistice Agreement, also agreed that a violation had occurred. Article 1, Paragraph 6 of the Armistice Agreement prohibits any hostile acts within, from, or against the DMZ, while Article 1, Paragraph 7 states that permission from the Military Armistice Commission is required to cross the Military Demarcation Line (MDL).

 With both the South Korean military and the UNC officially declaring that North Korea violated the Armistice Agreement, attention is turning to how it will respond.

 Defense Minister Kang Shin-chul confirmed before the National Assembly National Defense Committee on Tuesday that the incident was caused by a mine planted by North Korea, stating that the South would take corresponding measures.  

 While the scope of South Korea’s potential countermeasures is drawing considerable attention, options under discussion include stepped-up surveillance and patrols along the MDL, as well as tactical measures against North Korean soldiers who cross the line.

 However, resolving the issue has become more difficult as North Korea has categorically denied that the explosion was caused by its mines. 

At the same time, some point to how the strong stance taken by the South Korean military after the 2015 wooden-box mine incident led to officials from both Koreas engaging in dialogue, after which the North issued an expression of regret.  

 However, others warn that using the previous case as a precedent could trigger a major crisis.

 “We cannot resort to the same measures as in 2015, as the locations of the mines and the international situation have changed,” said Chang Yong-seok, a visiting scholar at Seoul National University’s Institute for Peace and Unification Studies.

“While the South Korean government should remain firm in voicing its objections and maintain a high state of readiness, it should exercise restraint and avoid kinetic clashes,” he said. 

 The incident has also highlighted the need to clarify the boundaries of the MDL, which played a part in the incident. 

 More than 70 years after the Korean War armistice, the two Koreas still have differing understandings of the MDL, and the latest incident highlights the growing potential for clashes along the border.

 Kim stated that the North’s soldiers have “never set foot for more than a half century” over the border, and claimed that its efforts to set up barriers on the southern border are a “thorough exercise of sovereignty unrelated with any military purpose.”

 “As North Korea is denying involvement, it is possible that we will engage in a back-in-forth to clarify the exact situation surrounding this incident,” said Kim Sung-bae, the chairperson of the Institute for National Security Strategy.

 “While inter-Korean relations may be hostile, the two Koreas and the UNC must engage in dialogue to discuss various issues, including the demarcation of the MDL, for our separate interests — the North is invested in demarking the MDL, while we wish to prevent any accidental conflict,” he added. 

 “Even if there is a possibility that Pyongyang will not accept offers of communication, we do need to reach out to engage in a conversation over the demarcation of the MDL and other issues to prevent accidental clashes,” Chang stressed.
