North Korea's Troops in Russia's War, Explained
North Korea has gone from quietly denying involvement to being one of Russia's most important wartime partners — supplying troops, artillery shells, and now negotiating a formal five-year military pact.
The numbers
The full explanation
How this started: Kursk, October 2024
Ukraine’s surprise August 2024 incursion into Russia’s Kursk region put Russian territory under sustained occupation for the first time since WWII. Facing a manpower gap it couldn’t fill fast enough, Russia turned to its 2024 mutual defense treaty with North Korea. The first North Korean units — trained at Russian bases, issued Russian equipment and forged documents attributing them to Russia’s Tuva region — arrived in the Kursk combat zone by Oct 23, 2024. Both governments denied it for six months before jointly confirming it in April 2025.
The casualties were real and significant
North Korean troops suffered heavily in their first modern combined-arms war: South Korea’s intelligence service and UK Defence Intelligence both estimated over 6,000 killed or wounded by mid-2026 — more than half the original deployment. Pyongyang sent reinforcements anyway, including a further 3,000 troops in early 2025, and 1,100 wounded soldiers who’d returned home were reportedly slated to return to the front. Whatever the human cost, Russia has praised the results, and North Korea has gained real combat experience against a modern, drone-saturated battlefield, plus Russian technical assistance upgrading its own weapons systems.
From battlefield partner to formal ally
By August 2026, the relationship moved beyond ad hoc troop deployment. Russian Defense Minister Belousov traveled to Pyongyang to propose a formal five-year (2027-2031) military cooperation plan — an attempt to institutionalize what’s so far been a series of individual arrangements. South Korea’s Ministry of National Defence says North Korea continues preparing further troop deployments but has detected no signs one is imminent, following Ukrainian President Zelensky’s claim that Pyongyang was preparing to send up to 50,000 additional troops — a claim North Korea’s Kim Yo Jong publicly denied.
Why this matters beyond Ukraine
A formalized Russia-North Korea military pact would be the most significant structural change to North Korea’s alliance posture since the Korean War armistice. It gives Pyongyang a great-power military patron actively at war, hands-on modern combat experience for its officer corps, and — per US and South Korean assessments — likely technology transfer covering satellites, submarines, and missile guidance. For Russia, it’s a manpower and artillery-shell pipeline that’s let it sustain offensive operations longer than its own mobilization alone would allow.
FAQ
How many North Korean troops are actually in Russia right now?
Estimates vary; South Korea's NIS put the figure near 11,000 stationed in Kursk Oblast at the start of 2026, with additional reinforcement waves since. No fully current, confirmed total exists.
Has North Korea officially admitted this?
Yes — both Russia and North Korea confirmed the deployment in exchanged statements on April 26-28, 2025, after six months of denial.
Is a new North Korea-Russia treaty actually happening?
As of late August 2026, it's a proposal raised by Russia's defense minister, not yet a signed agreement. South Korea's own assessment is that further deployment is being prepared but isn't imminent.
