The Guardian reports that over 150,000 tonnes of fuel, mostly diesel, was shipped from South Korea to Russia via sanctioned tankers in July and August.

The shipments involved seven tankers making 14 voyages to Russia’s far east, according to an analysis of port records and ship-tracking data.

Isaac Levi, an analyst at the Centre for Research on Energy and Clean Air (CREA), criticized the move, stating, “It is shocking that EU-sanctioned tankers loaded fuel at South Korean ports and carried it to Russia.”

Levi added, “This undermines the sanctions regime and South Korea’s support for Ukraine.” Seoul has provided humanitarian aid and non-lethal military supplies to Ukraine, pledging $2.3 billion in support, mostly in loans.

South Korea has long sought to balance its support for Ukraine with its desire to improve ties with Russia. Moscow has signaled interest in restoring relations with South Korea, including trade ties.

While the fuel trade does not appear to breach South Korean law, it risks making Seoul look like a weak link in western efforts to pressure Russia.

The shipments come amid tensions over the transfer of two North Korean prisoners of war to South Korea, which Seoul says was meant to remain secret.

Ukraine has been targeting Russian oil facilities, leading Russia to impose restrictions on its own fuel exports. Russia’s fuel oil exports fell to 591,000 barrels a day in August, down from the average 860,000 bpd in 2025.

Ukraine’s motive in attacking Russia’s energy facilities is to increase domestic pressure on the Russian president, according to Beauchamp, a commentator.

President Donald Trump has called for an end to the war, arguing that Russia has 'lost control' of its diesel industry due to the ongoing fighting with Ukraine.

What this adds

It is unclear who owned or sold the fuel, as South Korean port records do not show this information.

The fuel trade involves vessels sanctioned by some of Seoul’s western partners, but it does not breach South Korean law.

South Korea’s measures against Russia mainly rely on export controls on goods such as industrial machinery, electronics, and vehicles.

Background

Ukraine's announcement of the transfer of two North Korean prisoners of war (POWs) to South Korea has angered Seoul, leading to demands for an apology and explanation.
