'From Mines to Barriers' Frontline North Korea... [Yang Nak-gyu's Defence photo]

It has been confirmed that North Korea is recently constructing concrete barriers along the Military Demarcation Line (MDL). Military authorities are closely monitoring one of the barriers, which stretches several hundred meters in length, to see if it is part of a massive wall connecting the 248 km-long Demilitarized Zone (DMZ) from east to west. If a new barrier is erected beyond the 248 km MDL dividing North and South Korea, 35 years after the fall of the Berlin Wall in Germany, it is expected to symbolize the advent of a ‘new Cold War’ born from the confrontation between China, Russia, and the United States, becoming a ‘second Berlin Wall.’

Since North Korea defined inter-Korean relations as those between ‘hostile two states,’ it has consecutively taken measures to sever physical connections. At the end of last year, North Korean State Affairs Commission Chairman Kim Jong-un defined inter-Korean relations not as ‘kin’ but as ‘warring belligerent states.’ In his January address to the Supreme People’s Assembly, he declared, "We must implement phased measures to thoroughly separate the conditions for North-South linkage in the border area, including completely severing the North side section of the Gyeongui Line," effectively announcing the severance of relations. North Korea’s recent construction of barriers in addition to the MDL fence is interpreted as an effort to physically formalize this ‘anti-unification’ directive beyond mere declarative meaning. Earlier, on the 9th, 20 to 30 North Korean soldiers armed with pickaxes and shovels crossed the MDL near Yeoncheon, Gyeonggi Province, but retreated after warning shots from South Korean forces; intelligence authorities view this as part of the barrier construction work.

Recently, signs have also been detected that North Korean troops are installing barricades around the MDL area. Previously, North Korea had planted landmines on the Gyeongui and Donghae land routes. Analysts suggest these actions carry more symbolic significance than tactical benefits. The construction of barriers along the DMZ is seen as an attempt to block defection routes and maximize visual impact through physical barriers to send messages domestically and internationally. In particular, there is speculation that Kim Jong-un’s building of walls to control the border reflects significant internal unrest within North Korea, to the extent that he needs to strengthen internal control.
