South Korea has demanded an official explanation and apology from Ukraine after President Volodymyr Zelenskyy publicly disclosed the transfer of two North Korean prisoners of war to Seoul. The dispute centres on an alleged confidentiality agreement and could affect relations between Kyiv and one of its potential defence partners in Asia.
The disagreement comes as North Korean troops continue to be linked to Russia’s war against Ukraine. It also creates a diplomatic complication for Kyiv, which has sought greater military support from countries including South Korea.
South Korea says Ukraine broke a confidentiality agreement
South Korean President Lee Jae Myung’s office said Ukraine had unilaterally revealed information that the two governments had agreed to keep confidential. Seoul described the disclosure as a serious breach of trust and said it was considering further measures.
Senior presidential secretary Seong Ghi-hong said the South Korean government wanted an official explanation and apology. He also criticised a statement from a Ukrainian presidential aide suggesting that no confidentiality agreement had existed.
The dispute was triggered when Zelenskyy announced that Ukraine had transferred two captured North Korean soldiers to South Korea. He said the prisoners had not been easy to capture alive.
Lee responded publicly, saying he did not understand why Ukraine had broken the agreement and describing the decision as disappointing. Seoul’s position is that the issue was not simply the publication of information, but the alleged denial that a confidentiality arrangement had been in place.
Kyiv defends the public disclosure
Dmytro Lytvyn, an adviser to Zelenskyy, sought to minimise the disagreement. He said the Ukrainian president had only confirmed that the soldiers had been handed over to South Korea.
Lytvyn also argued that Ukraine is an open country and suggested that transferring prisoners secretly would have been unusual. That explanation has not satisfied Seoul, which maintains that the disclosure should not have been made without agreement.
The competing accounts leave the diplomatic status of the alleged agreement at the centre of the row. South Korea says its trust in the Ukrainian government has been seriously damaged, while Kyiv has defended the decision to make the transfer public.
Why the prisoners matter to the war in Ukraine
Ukraine captured the two North Korean soldiers during fighting last year. Their presence on the battlefield provided further evidence of Pyongyang’s military support for Moscow’s war effort.
One of the prisoners said he had served in a reconnaissance unit and had been trained in the use of some military equipment, although he said he had not been trained to operate Russian equipment. He also said he had been conscripted at the age of 17 and had served in the North Korean military since then.
The transfer to South Korea was politically sensitive because the prisoners’ fate could have consequences beyond the battlefield:
- It could intensify tensions between Seoul and Pyongyang.
- It could affect how North Korea presents its military involvement in Russia’s war.
- It could influence South Korea’s willingness to deepen practical support for Ukraine.
- It highlights the wider international consequences of North Korean involvement in the conflict.
Potential impact on South Korea’s policy towards Ukraine
South Korea has not supplied lethal weapons to Ukraine, citing domestic restrictions on providing military assistance to countries engaged in war. However, Seoul has considered requests for defensive equipment, particularly after North Korea sent troops to support Russia.
The diplomatic dispute could make future discussions more difficult. South Korea may view the incident as evidence that sensitive arrangements with Kyiv cannot be handled privately, while Ukraine may continue to argue that transparency is necessary when dealing with prisoners of war.
There is no indication in the source material that Seoul has formally ended discussions on defensive support. Nevertheless, the request for an apology introduces a new point of tension at a time when Kyiv is seeking international assistance against Russian bombardments.
North Korea and the wider diplomatic risk
Analysts cited in the report said the disclosure could also have consequences for relations between South and North Korea. Park Won-gon of Ewha Womans University said North Korea had used the deployment of its soldiers to support a heroic narrative for domestic propaganda.
Public confirmation that captured North Korean troops had been transferred to South Korea could, in Seoul’s view, fuel further hostility from Pyongyang. The issue is therefore connected not only to Ukraine’s wartime diplomacy but also to the security relationship on the Korean Peninsula.
The dispute demonstrates how developments on the Ukraine battlefield can affect countries far beyond Europe. North Korean military involvement has created a direct link between the war, European security and East Asian regional tensions.
What happens next?
South Korea is seeking an official explanation and apology from Ukraine. The immediate focus will be whether Kyiv acknowledges the alleged confidentiality agreement and whether the two governments can repair trust.
The disagreement may also be monitored by other countries considering military, humanitarian or diplomatic support for Ukraine. For Kyiv, maintaining confidence among potential partners is particularly important as Russia continues its attacks and Ukraine seeks additional defensive capabilities.
At this stage, the dispute concerns diplomatic conduct and the handling of sensitive information. It does not by itself establish a change in South Korea’s overall policy towards Ukraine, but it may complicate future discussions about military assistance.
Conclusion
South Korea’s demand for an apology places a new strain on its relationship with Ukraine after Kyiv disclosed the transfer of two North Korean prisoners of war. The episode combines questions about confidentiality, wartime transparency and the risks created by North Korea’s support for Russia. The next significant step will be whether Ukraine provides the explanation Seoul is requesting and whether both governments can prevent the dispute from affecting future cooperation.
