South Korea will withdraw additional embassy personnel from Ukraine, its Foreign Ministry announced on Tuesday, escalating a rare diplomatic row with Kyiv over the public disclosure of a secret transfer of two captured North Korean soldiers. The announcement is trending per news coverage.

Foreign Ministry spokesperson Park Doo-soon told a regular press briefing in Seoul that the decision followed Kyiv's failure to give a "constructive response" to South Korea's concerns, despite Seoul raising the issue "via multiple channels."

"This measure was taken because we judged it necessary to facilitate an amicable resolution of the issue and restore trust between the two countries," Park said, without saying how many staff would leave Kyiv.

What the withdrawal involves

Seoul is not closing its embassy. A chargé d'affaires will remain in Kyiv to maintain diplomatic communication, and all consular staff will stay in place to protect South Korean nationals in Ukraine, Park said.

The spokesperson also pointed to the security situation: persistent air strike threats across Ukraine had made it difficult to guarantee the safety of embassy personnel — a secondary factor alongside the political dispute.

The move is the second step in a downgrade that began earlier this month, when Seoul recalled its ambassador from Kyiv — a signal that a disagreement which might once have been handled quietly between foreign ministries has hardened into a public standoff.

How the dispute began: Zelenskyy's UNGA disclosure

The row traces back to September, when Ukrainian President Volodymyr Zelenskyy told the United Nations General Assembly that Ukraine had transferred two captured North Korean soldiers to South Korea.

The disclosure infuriated Seoul. South Korea said the transfer had been carried out under an understanding that it would remain confidential — secrecy intended to protect the two soldiers and their families back in North Korea, where relatives of defectors can face severe punishment.

By speaking about it publicly, Seoul argued, Kyiv had broken that understanding and put lives at risk.

The two North Korean soldiers at the centre of the row

North Korean troops have been fighting alongside Russian forces in the Ukraine war — most prominently in Russia's Kursk region, where Ukrainian forces have captured several North Korean personnel. Kyiv has repeatedly publicised the presence of North Korean soldiers as evidence of the war's widening scope.

The two soldiers transferred to the South are understood to have expressed a wish to defect rather than be repatriated to the North. Under South Korea's constitution, all North Koreans are considered citizens of the Republic of Korea, and those who reach its territory and seek to defect are generally allowed to stay — a legal framework that made the transfer possible in the first place.

Seoul's insistence on confidentiality reflects the stakes: North Korea treats defection as a grave crime, and public knowledge that specific soldiers have gone south can endanger families left behind. That is why, in Seoul's telling, the secrecy around the operation was not a courtesy but a condition.

Escalation: summoned ambassadors and an insufficient apology

After the initial disclosure, South Korea summoned Ukraine's ambassador in Seoul and warned of unspecified "further measures" if the dispute was not resolved.

Foreign Minister Cho Hyun said earlier this month that Kyiv had sent a message that "included words of apology" over Zelenskyy's remarks — but that it fell short of "the level" Seoul had in mind.

Tuesday's announcement is the "further measure" Seoul had been threatening: a partial drawdown of its diplomatic presence, calibrated to register displeasure without severing ties.

Ukraine's response: "the matter is closed"

Kyiv, for its part, has signalled it sees little left to discuss. Last week, Ukrainian Foreign Minister Andrii Sybiha told the RBC-Ukraine news outlet that his government considered the matter closed.

Sybiha attributed the disagreement to differing interpretations of the confidentiality arrangements and said Ukraine had fulfilled all of its obligations. Ukrainian officials have also said "diplomacy must prevail over emotions" in relations between the two countries — a formulation that implicitly frames Seoul's reaction as excessive.

That gap — Seoul demanding a fuller accounting, Kyiv insisting the file is shut — is precisely what Park Doo-soon described on Tuesday as the lack of a "constructive response."

Why this row matters beyond the two capitals

The dispute is a rare public crack in the coalition backing Ukraine. South Korea has been one of Kyiv's most important Asian partners, providing substantial non-lethal and humanitarian aid while stopping short of direct weapons transfers — a line Seoul has debated but held, partly over escalation fears involving North Korea and Russia.

The episode also illustrates how the war's human dimensions — prisoners, defectors, families — keep spilling into diplomacy. The presence of North Korean troops in the conflict has been a recurring flashpoint, from the swirl of rumours around Kim Jong Un's health and whereabouts to Western charges that Pyongyang runs sanctions-evasion networks such as the laptop-farm schemes targeted by US prosecutors.

For Ukraine, the row is an unwelcome distraction at a moment when its diplomacy is already stretched — with US-brokered peace talks in Oslo under way and American military support, including Patriot missile deliveries, facing new complications in Washington.

What happens next

Seoul has framed the staff withdrawal as a step toward resolution rather than rupture: the chargé d'affaires stays, consular services continue, and the stated goal is to "restore trust." The ball, in South Korea's telling, is in Kyiv's court — a fuller response could reverse the downgrade.

But with Ukraine publicly treating the matter as closed, a quick reconciliation looks unlikely. The most probable outcome is a frozen, functional relationship: diplomatic channels open, consular work continuing, and the ambassador's chair in Kyiv empty until one side decides the row has served its purpose.

Watch for whether Seoul follows through with any of the additional measures it has hinted at — and whether Kyiv's "closed" stance survives the first quiet diplomatic contact aimed at reopening it.

Meanwhile the border itself is heating up, as Pyongyang threatens escalation at the DMZ and Seoul promises a decisive response.
