South Korea’s Ministry of Foreign Affairs announced it will pursue legal action against alleged illegal fuel shipments to Russia if claims made by an adviser to Ukrainian President Volodymyr Zelenskyy are confirmed. The diplomatic friction stems from accusations that 176,000 tonnes of fuel moved through sanctioned tankers during July and August.
South Korea Denies Shipping Fuel to Russia
Vladyslav Vlasiuk, an adviser to the Ukrainian president on sanctions policy, stated on Wednesday that 176,000 tonnes of fuel were shipped from South Korea to Russia via sanctioned tankers in July and August. The South Korean presidential office quickly dismissed the findings, arguing they contradict Seoul’s established sanctions framework. “Since Russia’s invasion of Ukraine, our government has consistently implemented sanctions and export controls against Russia in close cooperation with the international community,” South Korean presidential spokesperson Kang Yu-jung said on Wednesday, according to the Yonhap news agency.

South Korea’s Foreign Ministry stated on Thursday that it had not confirmed whether South Korean fuel, including diesel, had been exported to Russia. Officials added that exports of certain products, such as diesel and jet fuel for commercial purposes, were not included in a South Korean exports control list to Russia. Seoul has urged Kyiv to verify facts prior to public statements. “We ask that Ukraine also refrain from distorting the relevant policies of the Republic of Korea without sufficient verification of the facts and making public remarks that can damage international trust,” Kang added.
Diplomatic Fallout Over Prisoner Disclosures
The fuel export dispute arrives amid broader strains in bilateral relations between Seoul and Kyiv. Tensions escalated over the prior couple of weeks after South Korea accused President Zelenskyy of unilaterally disclosing to the United Nations General Assembly that Kyiv had transferred two North Korean prisoners of war to South Korea. Seoul demanded an official apology, claiming a non-disclosure agreement was breached. Kyiv maintained that no such agreement existed.
Concurrently, geopolitical alignments involving Pyongyang and Moscow remain tight. The two countries signed a mutual defense treaty in 2024. According to estimates from both Ukrainian and South Korean sources, approximately 14,000 to 15,000 North Korean soldiers have been deployed to support Russian military operations in Ukraine. North Korea and South Korea remain technically at war, as the 1950–1953 Korean War concluded via an armistice rather than a formal peace treaty.
