The presidential office of South Korea has issued a sharp demand for official explanations and an apology from the Ukrainian side. The unprecedented diplomatic crisis was triggered by an incident involving the transfer of two captured North Korean military personnel who had previously fought alongside the Russian army and were captured by Ukraine's Defense Forces in the Kursk region.

Essence of the Diplomatic Conflict and Seoul's Accusations

According to a statement by Senior Presidential Secretary for Public Relations Song Ki-heon, Kyiv violated previously agreed confidentiality terms. Seoul claims that the Ukrainian side itself insisted on keeping the operation secret due to fears of domestic criticism in Ukraine over a missed opportunity to exchange the Korean prisoners for Ukrainian servicemen. South Korea agreed to this step out of humanitarian security considerations, but Ukrainian President Volodymyr Zelenskyy openly announced the soldier transfer from the UN General Assembly rostrum.

Contradictory Data

This incident clearly reveals contradictions in the official statements of both sides. The leadership of South Korea, including President Lee Jae-myung and advisor Song Ki-heon, insists on the existence of a strict verbal or written non-disclosure agreement regarding the prisoner transfer. Meanwhile, the Ukrainian side reportedly denied the existence of any such secret agreements following the UN speech. Such discrepancies have severely undermined trust between Seoul and Kyiv, threatening future bilateral security cooperation.

Background and Humanitarian Aspects

To recap, two North Korean servicemen were captured by Ukrainian troops in Russia's Kursk region back in January 2025, becoming the first living North Korean prisoners of war since Pyongyang joined the conflict. The prisoners themselves expressed a desire to go to South Korea. Seoul had long refused to officially confirm their arrival, citing concerns for the safety of the defectors and their relatives remaining in the North. Now, due to the public disclosure of information, bilateral diplomatic relations have suffered a major blow.
