- Kim Jong Un said plans to strengthen front‑line units on the border with South Korea to make it an “impregnable fortress”, at a meeting of division and brigade commanders on May 17.
- Kim Jong Un called for adjusting the training system and expanding practical drills to reflect changes in modern warfare and North Korea’s military development.
- Kim Jong Un urged redefining operational concepts in line with rapid modernization of military and technical equipment, and applying them to unit combat training.
- Kim Jong Un stressed ideological loyalty and vigilance against the “archenemy”, a term used for South Korea.
- South Korea’s Unification Ministry said the meeting appeared to be Kim Jong Un’s first reported meeting with division and brigade commanders since he took power, and that Seoul would continue to manage military tensions and seek to build trust.
- South Korea’s Joint Chiefs of Staff reported that North Korean troops have stepped up fortification work since March near the land border, including building walls.
- Hong Min, senior research fellow at the Korea Institute for National Unification, said Kim’s reference to fortifying the “southern border” suggests possible strengthening of maritime boundaries, and that the emphasis on modern warfare likely reflects lessons from Ukraine and Middle East conflicts.
Why it matters: Kim’s push to turn the DMZ into an impregnable fortress signals a heightened defensive posture, prompting Seoul to reaffirm its commitment to managing tensions and building trust while monitoring North Korea’s intensified fortification work and the broader shift toward modern warfare tactics.
