According to South Korean intelligence, approximately 6,000 North Korean troops deployed to support Russia in the ongoing war against Ukraine have been either killed or wounded. This information highlights the significant involvement of North Korean forces in the conflict, illustrating the extent of military collaboration between North Korea and Russia. The report indicates that about 10,000 combat troops and 1,000 engineer troops are stationed in the Kursk region of Russia, actively engaging in military operations supporting Moscow's efforts in Ukraine.

In addition to the casualty figures, the intelligence agency notes that around 1,100 North Korean soldiers who had returned to their country in December 2025 may be redeployed to Russia, further emphasizing the persistent military partnership between the two nations. Despite suffering heavy losses, North Korean forces appear to be gaining invaluable combat experience and military tactics through their involvement, suggesting that these operations are seen as both a contribution to Russian efforts and a training opportunity for the North Korean military.

The collaboration between North Korea and Russia raises concerns about the long-term implications of their military relationship, particularly in the context of regional security dynamics. As North Korea continues to adapt and modernize its military capabilities with assistance from Russia, it poses potential challenges for neighboring countries and the international community, particularly regarding the shifting balance of power in East Asia.
