Seoul threatens 'further action' if Ukraine does not apologise over North Korean prisoner transfer

South Korea's President Lee Jae Myung has threatened unspecified "further action" against Ukraine unless Kyiv issues a public apology for revealing that two North Korean prisoners of war had been sent to the South. Ukraine's leader Volodymyr Zelensky disclosed the transfer at the UN general assembly last week, angering Seoul, which said the arrangement was meant to remain secret.

Ukraine's Foreign Minister Andrii Sybiha described the row as a "diplomatic misunderstanding" on Thursday and said Kyiv was "working" to resolve it. Lee rejected that characterisation on X, saying the matter concerned "the dignity of the Korean people and the nation". He also accused Kyiv of "attempting to provoke a war on the Korean Peninsula".

The dispute has become a domestic problem for Lee. His office said Ukraine had requested the secrecy, partly to protect the soldiers' families and to avoid criticism that Kyiv had forfeited a chance to exchange them for Ukrainian prisoners of war. Zelensky's office responded that the two countries had no such confidentiality agreement, further escalating the situation. South Korean opposition figures have accused Lee of covering up the transfer to appease Pyongyang.

The two soldiers were among thousands of North Koreans supporting Russia in the Ukraine war, and had earlier told local media they wanted to be sent to South Korea.

Sybiha said he hoped the situation would be resolved "in the very near future", adding: "For us, South Korea is an important country." The nature of Lee's "further action" remains unspecified.

Analysis

Why This Matters

The dispute threatens to fracture a relationship between two countries that share a common interest in opposing Russia's war in Ukraine, at a delicate moment in that conflict.
President Lee faces domestic political fallout, with opposition figures accusing him of covering up the transfer to appease Pyongyang.
How the two North Korean soldiers are handled could set a precedent for future prisoners from the thousands of North Korean troops reportedly fighting alongside Russian forces.

Background

The two countries have been deepening ties since Russia's full-scale invasion, with South Korea providing aid to Ukraine while stopping short of lethal military support. The transfer of the two prisoners to Seoul was treated by both governments as confidential, though the terms of that understanding are now disputed. The incident also lands against the backdrop of the long-standing state of war between North and South Korea, which remain divided by a heavily fortified border.

Key Perspectives

South Korea: Seoul sees the disclosure as a breach of confidence touching national dignity, has demanded a public apology, and has warned of unspecified further action if one does not come. Ukraine: Kyiv calls the episode a diplomatic misunderstanding, says it is working to resolve it, and denies that any confidentiality agreement existed, according to Zelensky's office. South Korean critics: The domestic opposition accuses Lee of covering up the transfer to appease Pyongyang, adding political pressure to the standoff.

What to Watch

Whether Ukraine issues the public apology Seoul is demanding, and how quickly.
What form Lee's unspecified "further action" takes, and whether it affects diplomatic, economic or military cooperation.
Whether the South Korean opposition's accusations fuel further domestic scrutiny of the president's handling of the affair.
