Seoul demands apology from Kyiv

What's happened

South Korean President Lee Jae Myung has demanded an apology after Ukrainian President Volodymyr Zelenskyy publicly said Kyiv transferred two captured North Korean soldiers to South Korea. Seoul says the transfer was meant to be confidential and accuses Ukraine of breaching an agreement; Kyiv denies any nondisclosure pact and calls the matter a diplomatic misunderstanding.

What's behind the headline?

What is driving the dispute

• South Korea is treating Zelenskyy's public disclosure as a breach of a confidentiality understanding that Seoul says existed to protect the soldiers and their relatives in North Korea.
• Ukraine is framing the public remark as part of a broader effort to highlight North Korean involvement in the war and to rally international support.

Risks and consequences

• The row will increase diplomatic friction between Seoul and Kyiv and will force both governments to repair trust before cooperation can resume at previous levels.
• Lee's public demand for an apology and his threat of "further action" will push Seoul to escalate diplomatically if Kyiv does not deliver a formal explanation.

Who benefits

• Domestic political actors in South Korea are benefiting politically by pressing for accountability; opposition parties are using the disclosure to criticise the president.
• Ukraine benefits from increased global attention on North Korea's role in the war, which will support Kyiv's case for more international backing.

Likely next steps

• Seoul will press for a formal apology and may adopt measured diplomatic steps — public statements, intelligence briefings to lawmakers, and possible restrictions on joint initiatives — if Kyiv refuses to satisfy its demands.
• Kyiv will continue to call the situation a diplomatic misunderstanding and will work through diplomatic channels to resolve it, but failure to issue a public apology will prolong the dispute.

Bottom line

This dispute will test a fragile diplomatic groove: Seoul will prioritise the safety of the two soldiers and their families and will use diplomatic pressure to force Kyiv into a clearer, public accounting. Kyiv will weigh the cost of an apology against the domestic and strategic benefits of exposing North Korean involvement in the conflict.

How we got here

Ukraine has captured two North Korean soldiers from fighting in Russia's Kursk region and has transferred them to South Korea after the men expressed a desire to resettle there. South Korea has said the move required secrecy to protect the soldiers and their families and to avoid diplomatic fallout; Ukraine announced the transfer at the UNGA and denied a confidentiality agreement.

Our analysis

BBC Business reports that President Lee has threatened "further action" if Ukraine does not apologise after President Zelensky disclosed the transfer at the UN and Ukraine described the situation as a "diplomatic misunderstanding" (Kelly Ng, BBC Business). AP News records Seoul's closed-door intelligence briefing to lawmakers, saying Ukraine denied a confidentiality agreement and that South Korea's National Intelligence Service found no apology had been offered through official or unofficial channels (AP). AP also reported that Zelensky announced the transfer at the U.N. General Assembly and that Seoul immediately accused Kyiv of breaching a nondisclosure agreement (AP, 28 Sep). Bloomberg quoted Seoul's presidential office saying the transfer proceeded "after multiple rounds of discussions through various channels" and that Ukraine had requested confidentiality (Bloomberg). Al Jazeera and Arab News published Seoul's statement via Yonhap that the nondisclosure was meant to protect the soldiers and their families and that the presidential office was "reviewing additional measures" (Al Jazeera; Arab News). These accounts split on one point: Seoul's officials and Yonhap frame a prior confidentiality understanding and warn of concrete consequences, while Ukrainian sources and some Western reporting present Kyiv's announcement as either part of strategic messaging or a misunderstanding. Direct quote examples: "The presidential office expresses strong regret over Ukraine's unilateral disclosure and its subsequent false announcement that there had not been a non-disclosure agreement," Seong Ghi-hong, senior presidential secretary for public relations (Yonhap, cited by Arab News). "We are working on it. For us, South Korea is an important country," Ukraine's Foreign Minister Andrii Sybiha said when describing efforts to resolve the issue (Kelly Ng, BBC Business).
