North Korea's New Export to Russia Is Its People

When Ukraine's engineers took apart a North Korean KN-23 ballistic missile in early 2024, after it had been fired at Russia's request, the workmanship looked a generation out of date: solder joints of a quality they compared to 50-year-old technology, an engine half again larger than its Russian equivalent, and civilian-grade electronics bought to slip past sanctions ^[1]. It was a crude machine, sold by a country peddling what it had. Keep that image, because what Pyongyang sells Moscow now barely resembles it. The first years ran on volume. Roughly 350,000 artillery shells a month; more than 20,000 soldiers in four waves; about 20,000 containers of materiel moving out of the North Korean port of Najin — Rajin in South Korea's transcription ^[2]. And almost none of it for cash. South Korea's Institute for National Security Strategy put the cash share of the exchange at 4 to 19.6 percent ^[2]; the rest came back as air-defense systems, electronic-warfare gear, and technical feedback on the Hwasong missiles themselves ^[3]. Pyongyang was bartering ammunition for the knowledge to build better weapons — including, dryly, the Hwasong-11s whose failure rate monitors put near 50 percent ^[3]. The missile industry whose crudeness opened this story is the one Russia was paid to improve. The center of gravity has since moved from product to person. Up to 12,000 North Korean workers are now assigned inside the Alabuga complex in Tatarstan, where Russia produces Geran attack drones ^[4]. An investigation published this week traced a Russian recruitment network — a platform called KNDR.su — funneling North Korean workers into Russian plants, including a factory that makes military rations, on student visas that dodge UN sanctions, with the state seizing most of their wages and holding their families as leverage ^[5]. South Korea's intelligence service has counted 5,000 North Korean construction troops rebuilding infrastructure in the Kursk region, plus 1,000 mine-clearing engineers — not fighting at the front, but sinking into the landscape behind it ^[6]. The state takes 70 to 90 percent of what these workers earn ^[4], so the same wages that keep the drone lines running also keep Pyongyang's weapons programs financed. Researchers at CSIS and the Bush Institute gave the challenge that transfer creates a name.

The North Korean technicians at Alabuga are learning to mass-produce attack drones, and the knowledge travels home with them. Pyongyang is not just renting out its people; it is importing the production line. Then the plumbing. The exchange now rides on physical arteries that are harder to watch than the rail lines it used to take. In April the two countries linked the first road bridge between them across the Tumen River, and opened it in September: two lanes, a capacity of 300 vehicles a day, and far harder to monitor by satellite than the existing rail ^[7][8]. Russia is also modernizing the port of Rajin, and in April the two began the first direct flights between Moscow and Pyongyang — Aeroflot, weekly — so workers and officials no longer need a third country ^[9][10]. Prime Minister Mishustin framed the bridge in the language of integration.

I am convinced that the expansion of transport infrastructure near the border will give a powerful boost to the further development of trade, economic, technological, scientific and cultural cooperation between the Russian Federation and the Democratic People's Republic of Korea. — Mikhail Mishustin

He went further, casting the North Korean troops who fought for Russia as heirs to a Soviet hero who once saved Kim Il Sung ^[8]. That is the language of a relationship being presented as permanent, not as a wartime convenience. There is a demand side to all this, and it deserves to be flagged plainly: Russia's labor minister told Vladimir Putin in July 2025 that the economy will need 2.4 to 3 million additional workers by 2030, after a war that has killed or wounded more than a million working-age men and a birth rate at a 25-year low, with the Central Asian migrants who once filled the gap now deterred by new rules and open hostility ^[11]. No source connects that projection to the North Korean deployments — the fit is this column's inference, not anyone's stated plan. But the shape of the demand matches what is already arriving: the drone-factory shifts, the reconstruction brigades, the workers on student visas. Amnesty concluded last month that Russia is trafficking people from the Global South into its military through fraudulent job ads ^[12]; the North Korean flow is the organized, state-brokered variant of the same hunger for bodies. And Pyongyang is not the only neighbor pouring concrete — China has been widening its own bridges and rail into North Korea at the same time ^[13][14]. Nor is Pyongyang pretending the arrangement is temporary anymore. Even with roughly a third of its deployed troops killed or wounded, it has kept ordering new waves ^[15]. It dismisses the monitors who documented the deployments.

It argues that the military ties with Russia are a lawful exercise of sovereign rights under the mutual-defense treaty ^[16]. Regimes that stop hiding an arrangement and start defending it as sovereignty are telling you it is meant to last. A ceasefire would stop the shells and the front-line rotations. It would not stop the drone-factory shifts, the Kursk rebuilding crews, or the 300 vehicles a day across the Tumen. That traffic keeps moving after the guns fall silent.
