North Korean POW Transfer Strains Seoul-Kyiv Ties After Zelensky's UN Disclosure

Two North Korean soldiers captured by Ukrainian forces early last year have become the unlikely center of a diplomatic dispute between Seoul and Kyiv. The men were among thousands of North Korean troops deployed to Russia to fight alongside Moscow's forces, primarily in the Kursk border region, in exchange for economic and military aid flowing back to Pyongyang. Both soldiers expressed a desire to be transferred to South Korea, and both countries quietly arranged for that to happen. Then, during his address to the United Nations General Assembly last week, Ukrainian President Volodymyr Zelensky announced the transfer publicly, describing the soldiers as difficult to capture alive because North Korean troops are trained to kill themselves rather than surrender. "This is how they raise people in the North," Zelensky said. "They drill into them that they must die."

South Korea's government was blindsided. President Lee Jae Myung said the two nations had reached a "clear understanding" to keep the operation confidential, and he called Zelensky's disclosure "very disappointing." The concern was not abstract. Both soldiers had already been photographed by South Korean media upon arrival, making them identifiable. With their faces now potentially known beyond Seoul's control, their families back in North Korea face a grave risk. Cho Seong-ryoul, a former policy adviser to South Korea's presidential national security office, told AFP that the families "are certain to face persecution in the North." The revelation transformed what was meant to be a discreet humanitarian operation into a public liability for people who had no say in how their story would be told.

One of the two soldiers was conscripted at age seventeen and served in a reconnaissance unit. Upon arrival in South Korea, both men will follow the standard protocol for North Korean defectors: interrogation by South Korea's intelligence agency, followed by roughly twelve weeks at Hanawon, a government resettlement facility where arrivals learn to navigate South Korean society—how to open a bank account, drive a car, access healthcare. But these two are unlikely to follow that ordinary path. Ahn Chan-il, a researcher originally from North Korea, told AFP that the soldiers will probably be housed separately from typical defectors, possibly at a secure undisclosed location or near a military hospital if they require medical care. "Defectors with sensitive backgrounds—such as former intelligence operatives, diplomats or those with access to state secrets—are typically kept separately from other arrivals," he said.

How Pyongyang will respond remains uncertain. North Korea has a documented history of retaliating against defectors and their families. But Hong Min of the Korea Institute for National Unification suggested that the regime may choose restraint. If the government punishes the soldiers' families and word spreads among the families of other troops deployed to Russia, it could provoke unrest among people whose relatives are still fighting abroad. That political risk might outweigh the regime's desire for revenge. "With that in mind, Pyongyang may instead choose not to take action," Hong Min said.

The diplomatic fallout between Seoul and Kyiv cuts deeper than a single breach of confidence. South Korea has become a major arms exporter in recent years, particularly since Russia's invasion of Ukraine in 2022, including a multibillion-dollar deal with Poland. Yet Seoul has consistently refused to send lethal weapons to Ukraine, citing a longstanding policy against arming countries in active conflicts. Kyiv has repeatedly requested South Korean air defense systems—a request Seoul has not answered. Some South Korean lawmakers suspect Zelensky's public disclosure was calculated. Lawmaker Yoo Yeong-ha said Wednesday that Seoul's spy agency believes Zelensky "may have decided to disclose the transfer" hoping it would "generate public support in Seoul for providing Ukraine with weapons and other forms of assistance." If that was the intent, it appears to have backfired. Lim Eul-chul, a professor at Kyungnam University, told AFP that the incident could make Seoul even more reluctant to provide military support. "Arms transfers require an extremely high degree of trust, and Zelensky's move could make Seoul even more cautious," he said. What began as a quiet transfer of two soldiers has become a test of whether Seoul and Kyiv can rebuild the confidence necessary for deeper military cooperation.
