September 18, 2026

Summary

Ukrainian President Volodymyr Zelenskyy says North Korea may have sent between 30,000 and 50,000 soldiers to Russia to support the war in Ukraine. He warned that Russia may be giving these troops battlefield experience and training. Ukraine’s intelligence agency previously reported that North Korea was considering deploying up to 50,000 personnel in western Russia. The claims have not been independently verified. Any large-scale deployment could strengthen military cooperation between Moscow and Pyongyang. It could also give North Korea experience with modern combat technologies and tactics. Japan is watching the situation closely because of North Korea’s missile program and Russia’s military presence in the Indo-Pacific. Read the full article for the wider security implications.

Ukraine raises alarm over North Korean military support

Ukrainian President Volodymyr Zelenskyy has said North Korea may have already sent between 30,000 and 50,000 soldiers to Russia to support Moscow’s invasion of Ukraine. Zelenskyy made the assessment in a post on a messaging application on the 17th, warning that Russia could be providing North Korean troops with valuable battlefield experience and military training.

The claim has not been independently verified, and the Ukrainian president did not publicly provide detailed evidence in the statement. However, it adds to growing international concern about increasingly close military cooperation between Moscow and Pyongyang. The reported deployment would represent a significant expansion of North Korea’s involvement in the conflict and could further internationalize the war.

Reported plans for troops in western Russia

Ukraine’s Main Directorate of Intelligence said in August that North Korea was considering increasing the scale of its troop deployment to Russia to as many as 50,000 personnel. According to the Ukrainian agency, the troops could be stationed in western areas of Russia, near the border with Ukraine.

If confirmed, such a deployment could allow Russia to use North Korean personnel for support, logistics, engineering, or combat-related duties while giving North Korean forces direct exposure to modern warfare. The experience could be particularly important for Pyongyang, whose military has limited recent experience in a large-scale conventional conflict involving drones, precision weapons, electronic warfare, and satellite-supported operations.

A widening security partnership

The reported troop cooperation follows a broader strengthening of relations between Russia and North Korea. Both governments have opposed Western sanctions and criticized the United States and its allies. Their expanding partnership has raised concerns that military technology, ammunition, training, and battlefield knowledge could move in both directions.

For Russia, North Korean support could help ease pressure on its own military manpower and defense production. For North Korea, cooperation with Russia could provide economic assistance, diplomatic backing, and access to military expertise. Analysts have warned that any transfer of advanced weapons or sensitive technology could affect security calculations across Northeast Asia.

Why the issue matters to Japan

The developments are being watched closely in Japan. Tokyo has consistently viewed cooperation among North Korea, Russia, and other authoritarian states as a direct concern for regional stability. North Korea’s missile and nuclear programs already pose a serious challenge to Japan, while Russia’s military activity in the Indo-Pacific has added to the country’s security concerns.

Japan has strongly supported Ukraine and joined international sanctions against Russia, while also working with the United States, South Korea, and other partners to improve information-sharing and deterrence. A deeper Russia-North Korea military relationship could make coordination among these countries even more important.

The reported deployment also highlights how conflicts in Europe can have consequences in Asia. Military lessons learned on the Ukrainian battlefield may influence future operations elsewhere, while closer cooperation between Russia and North Korea could complicate efforts to prevent weapons proliferation and reduce tensions in the region. For now, the scale and role of any North Korean troop presence remain unclear, but Ukraine’s warning is likely to intensify international scrutiny of the relationship.
