SEOUL, Oct 2 — South Korean President Lee Jae Myung has threatened unspecified measures against Ukraine unless Kyiv acknowledges a confidentiality agreement that Seoul says covered the transfer of two captured North Korean soldiers and issues an apology.
"If the refusal to acknowledge the facts and issue a public apology continues, we will take additional measures," he said in a post on X (formerly Twitter) today.
Lee also expressed "grave regret" over what he described as Ukrainian remarks about an imminent military clash between North and South Korea, saying they amounted to encouraging war on the Korean peninsula.
Seoul and Kyiv have been locked in a diplomatic dispute since Ukrainian President Volodymyr Zelenskiy announced at the United Nations General Assembly last month that Ukraine had transferred two North Korean prisoners of war captured while fighting for Russia to South Korea.
Seoul subsequently accused Kyiv of breaching an agreement to keep the transfer confidential to protect the soldiers, while Ukrainian officials denied any such agreement existed.
Kyiv's Embassy in Seoul did not immediately reply to a request for comment on Lee's remarks.
'Neither side benefits from dispute'
The Ukrainian media reported that the country was seeking to mend ties with South Korea, quoting Foreign Minister Andrii Sybiha.
"I would not like to call this an incident. Let us say it is a diplomatic misunderstanding," Sybiha told the media at an event, according to a report on Thursday on news website nv.ua and other media.
According to South Korean media reports, a senior South Korean Foreign Ministry official told the media today that the countries' foreign ministers had been discussing how Kyiv could address Seoul's concerns, including a possible apology.
Foreign Minister Cho Hyun and Sybiha had been in direct contact, discussing what level of response Seoul was seeking and what Ukraine could accept, while taking into account Ukraine's wartime circumstances and the need to avoid causing either side a loss of face.
The dispute comes at a sensitive time for Lee's administration, which has sought to reduce tensions with North Korea and is also dealing with the political fallout from a recent landmine incident in the Demilitarised Zone that separates the two Koreas.
Seoul-based Korea Institute for National Unification senior fellow Cho Han-bum said any additional measures would most likely involve support South Korea already provides to Ukraine, including humanitarian, financial, and reconstruction assistance.
"Ukraine has more to lose than South Korea because it is receiving support from Seoul," he said.
South Korea has provided humanitarian and financial assistance to Ukraine since Russia's 2022 full-scale invasion and in July pledged an additional $100 million in non-lethal support on the sidelines of the NATO summit.
"However, neither side benefits from a prolonged confrontation," Cho said, noting that South Korea relies on Ukraine for information related to North Korea's military activities.
