South Korea's presidential office has demanded an official explanation and apology from Ukraine after Ukrainian President Volodymyr Zelenskyy publicly announced at the UN General Assembly that two captured North Korean prisoners of war had been transferred to South Korea. Seoul contends that the transfer was subject to a strict confidentiality agreement negotiated across multiple channels to protect the safety of the soldiers and their families and to avoid diplomatic fallout. Ukraine, however, denied the existence of a nondisclosure pact, stating that as an open country it only confirmed the factual handover, prompting Seoul to warn that bilateral trust has been severely damaged.

// Background

Pyongyang deployed troops to support Russia's war in Ukraine in 2024, sending an estimated 14,000 to 15,000 personnel primarily to Russia's Kursk region. The two POWs were captured alive in January 2025. Because South Korea legally regards the North as part of its territory and North Korean defectors face persecution if repatriated, discussions were held between Seoul and Kyiv regarding their resettlement. South Korea has provided humanitarian aid and sanctions support to Ukraine but maintains a policy against providing direct lethal military support, and Seoul is cautious about disruptions to potential diplomatic dialogue with North Korea.

// Key Developments

  • South Korea demanded an official apology and explanation from Ukraine for publicly revealing the transfer of two North Korean POWs.
  • Seoul accused Kyiv of breaching a confidentiality agreement and falsely claiming no nondisclosure agreement existed.
  • Ukrainian President Volodymyr Zelenskyy announced the transfer during his address to the 81st UN General Assembly.
  • Ukrainian presidential adviser Dmytro Lytvyn defended Kyiv's disclosure, arguing Ukraine is an open country and merely reported the fact.
  • The two soldiers were captured alive in Russia's Kursk region in January 2025 and had expressed a desire to resettle in South Korea.
