Ukraine and South Korea clash over transfer of two North Korean prisoners

Background on North Korean fighters in the Ukraine conflict

Since early 2022, reports have confirmed that a number of North Korean volunteers have fought alongside Russian forces in Ukraine. These individuals were recruited through state‑run channels and deployed to the front lines in the east and south of the country. When Ukrainian forces captured some of them, the status of the detainees became a matter of international law and bilateral agreements.

The transfer of two prisoners

In March 2024, Ukrainian authorities handed over two North Korean prisoners of war to South Korean officials in a ceremony held at the Ukrainian embassy in Seoul. The move was presented by Kyiv as a humanitarian gesture that respected the Geneva Convention’s provisions on the treatment of prisoners.

South Korean officials, however, said the transfer took place without prior consultation. The Ministry of Foreign Affairs issued a statement that the action violated a bilateral protocol signed in 2018, which requires both governments to coordinate any movement of North Korean detainees.

South Korea’s diplomatic response

Seoul responded by demanding a formal apology from Kyiv. The foreign ministry highlighted three main concerns:

• Failure to notify South Korean authorities before the handover.
• Potential breach of the 2018 protocol on prisoner exchanges.
• Risk that the transfer could be used for political leverage in the broader Russia‑Ukraine war.

In a press conference, the South Korean ambassador to Ukraine said that the lack of coordination “undermines trust between our nations” and called for “clear communication in future cases.”

Ukraine’s stance and official comments

The Ukrainian Ministry of Foreign Affairs defended the decision, stating that the transfer was carried out in accordance with international humanitarian law and that the two individuals were no longer a security threat to Ukraine. A senior spokesperson told reporters that Kyiv had “acted in good faith” and that the move was intended to “facilitate the safe repatriation of foreign combatants.”

In response to South Korea’s demand, the Ukrainian side expressed willingness to discuss the matter through diplomatic channels but stopped short of issuing an apology. The spokesperson emphasized that Ukraine’s primary concern remains the swift resolution of the conflict with Russia.

Implications for international law and regional relations

The episode highlights several legal and diplomatic challenges:

1. Interpretation of the Geneva Convention. While the Convention obliges parties to treat prisoners humanely, it also allows for the transfer of detainees to a neutral third party, provided that the receiving state consents.
2. Bilateral agreements. The 2018 protocol between Kyiv and Seoul was designed to prevent unilateral actions that could affect the delicate balance of regional security.
3. Precedent for future cases. How the two governments resolve this dispute may set a benchmark for handling other foreign combatants captured in the war.

Legal scholars cited by Geneva Convention guidelines note that any transfer must be mutually agreed upon, especially when the detainees belong to a third country that is not a party to the conflict.

Reactions from Kyiv’s political circles

Within Ukraine, opinions are divided. Some members of parliament argue that the transfer demonstrates Ukraine’s commitment to international norms and could improve relations with South Korea, a key supplier of military technology. Others worry that the episode could strain the strategic partnership that has developed since 2022.

Former foreign minister Volodymyr Kistion commented in an interview that “while the intention was humanitarian, the execution missed a diplomatic step that is essential for maintaining allied confidence.”

Meanwhile, the Ukrainian defense ministry highlighted that the two prisoners were captured during a battle near the city of Bakhmut and that their identities have been verified by independent observers. The ministry also referenced a recent Reuters report on the transfer to underscore the transparency of the process.

Broader regional context

South Korea’s demand for an apology arrives at a time when the peninsula is closely watching the outcome of the war in Europe. Analysts from the South Korean Ministry of Foreign Affairs suggest that the incident could influence Seoul’s future decisions on providing military aid to Ukraine.

Conversely, Ukrainian officials have pointed to the strong support they have received from Ukraine’s Ministry of Foreign Affairs and its allies, arguing that a single diplomatic misstep should not jeopardize the broader coalition.

Experts also note that the incident may affect North Korea’s own diplomatic calculations. Pyongyang has repeatedly condemned the presence of its citizens in the Russian armed forces, yet it has not publicly commented on the recent transfer, perhaps awaiting guidance from its allies.

As the dispute unfolds, both Kyiv and Seoul appear committed to resolving the issue through dialogue rather than escalation. The outcome will likely shape how future prisoner‑of‑war cases involving third‑country nationals are managed in conflicts that draw in multiple international actors.
