South Korea’s Ministry of Foreign Affairs announced that the government will pursue legal action regarding any illegal fuel shipments to Russia should allegations made by an adviser to Ukrainian President Volodymyr Zelenskyy be officially confirmed. Speaking on Thursday, the Foreign Ministry stated it has not yet verified whether South Korean fuel, such as diesel, was actually exported to Russia. Furthermore, officials noted that certain products like commercial diesel and jet fuel are not currently featured on South Korea's export control list targeting Russia.

These developments follow a Wednesday dismissal by the South Korean presidential office regarding statements from Vladyslav Vlasiuk, an adviser to the Ukrainian president on sanctions policy. Vlasiuk had alleged that 176,000 tonnes of fuel were transported from South Korea to Russia aboard sanctioned tankers during July and August. The top Ukrainian sanctions official claimed these findings contradict South Korea's stated sanctions policy against Russia.

“Since Russia’s invasion of Ukraine, our government has consistently implemented sanctions and export controls against Russia in close cooperation with the international community,” stated South Korean presidential spokesperson Kang Yu-jung on Wednesday, according to the Yonhap news agency. She further urged Ukraine to avoid distorting South Korean policies without proper fact-checking and to refrain from public remarks that could undermine international trust.

Bilateral relations between South Korea and Ukraine have experienced friction over recent weeks following Seoul's accusations that President Volodymyr Zelenskyy unilaterally disclosed to the United Nations General Assembly that Kyiv had transferred two North Korean prisoners of war to South Korea. While Seoul demanded an official apology for what it claimed was a breach of a non-disclosure agreement, Kyiv maintained that no such agreement existed.

Meanwhile, Pyongyang and Moscow maintain strong relations, having formalized a mutual defence treaty in 2024. Intelligence estimates from both Ukraine and South Korea suggest that approximately 14,000 to 15,000 North Korean soldiers have been deployed to support Russian military operations in the war against Ukraine. South Korea and North Korea remain technically in a state of war, as the 1950–1953 Korean War concluded with an armistice instead of a formal peace treaty.
