• South Korea demands an apology from Ukraine for disclosing the transfer of North Korean POWs.
• Ukrainian President Zelensky announced the transfer at the UN General Assembly, causing diplomatic tensions.

South Korea's presidential office is demanding an official explanation and apology from Ukraine after President Volodymyr Zelensky revealed the transfer of two North Korean prisoners of war during his address to the United Nations General Assembly. Seoul claims Kyiv breached a non-disclosure agreement regarding the matter, which had been discussed through various channels, according to senior presidential secretary Seong Ghi-hong. He highlighted that the unilateral disclosure was a source of "strong regret," and indicated that South Korea's government was considering additional measures given the situation, as reported by SCMP and Channel News Asia.

The contentious transfer involved two North Korean soldiers captured while fighting for Russia, marking a significant diplomatic incident as Seoul accused Ukraine of compromising sensitive negotiations. According to India Times and Reuters, President Lee emphasized that public disclosure could provoke backlash against Ukraine for missing an opportunity to negotiate for the release of captured Ukrainian soldiers.

Following the incident, South Korea's foreign ministry summoned Ukraine's acting ambassador Andrii Vieshkin to lodge a formal complaint. Vice Foreign Minister Park Yoon-joo expressed concerns that the disclosure undermined trust between the two nations, and described the situation as damaging to their bilateral relations, as noted by India Times and BBC.

The North Korean soldiers, who had reportedly expressed a desire to defect to South Korea, became a focal point for wider diplomatic tensions, as Seoul remains sensitive to local and international reactions towards North Korea. A senior lawmaker's comments reflected ongoing criticism of President Lee's administration for its management of the situation, further complicating the already delicate dynamics between both Koreas and the ongoing conflict in Ukraine, according to Al Jazeera and BBC.

Seoul has long maintained a cautious approach regarding military assistance to Ukraine, despite increasing demands for support amidst the conflict with Russia, which has implications for South Korea's national security outlook and its longstanding policies regarding relations with North Korea and strategic partnerships with global allies, as explained by Reuters.
