South Korea says it is strictly enforcing its export controls on Russia and will take action under its laws if investigations confirm that fuel shipments from its ports violated domestic law. The statement, issued by the foreign ministry on Thursday, follows a Guardian investigation which found that more than 176,000 tonnes of fuel, mostly diesel, were loaded at South Korean ports in July and August and shipped to Russia’s far east.
FAKTA
- 176,000+ tonnes of fuel, mostly diesel, loaded at South Korean ports in July and August 2026 and shipped to Russia’s far east, according to a Guardian analysis of port records and ship-tracking data.
- Seven tankers made 14 voyages to Russian ports, mainly Vladivostok; three of the tankers were under UK and EU sanctions.
- Sanctioned vessels Layla (~57,000 tonnes of diesel from Ulsan), Astoria (~11,000 tonnes from Ulsan) and Chongchon (~26,000 tonnes via a ship-to-ship transfer off Yeosu) declared destinations including Japan and Singapore before sailing to Vladivostok.
- Buyers included Russia’s state-controlled Rosneft and NNK, according to data from maritime analytics firm Kpler.
- In August, Russia imported 368,000 tonnes of petroleum products by sea — the highest monthly total since February 2022 — with South Korea supplying 112,000 tonnes (31%), second only to India.
- Seoul says official trade statistics show no confirmed exports of diesel, jet fuel or gasoline to Russia through customs clearance from 2025 through August 2026.
- South Korea’s Russia export controls cover strategic items plus 1,402 non-strategic items subject to case-by-case authorisation; refined petroleum products are not covered, so loading them at South Korean ports does not itself violate domestic law. Outbound shipments to Russia fell to US$4 billion in 2025 from US$10 billion in 2021.
How the South Korea fuel shipments to Russia moved
The largest carrier was the sanctioned tanker Layla, which made two trips from Ulsan in south-eastern South Korea to Vladivostok on 19 July and 10 August, carrying 57,000 tonnes of diesel in total. On its first trip, Layla told South Korean authorities it was heading for Vladivostok; on the second, it declared Niigata in Japan before sailing to the Russian Pacific port instead.
The Russian-flagged Astoria, also under sanctions, loaded nearly 11,000 tonnes of petroleum products at Ulsan on 1 August and declared Japan as its destination before travelling to Vladivostok. A third sanctioned vessel, Chongchon, never berthed at a port: it took on about 26,000 tonnes of fuel from the unsanctioned Celeste I at an anchorage off Yeosu in early August, declared Singapore, and headed for Vladivostok. The owners and managers of the tankers did not respond to requests for comment, and South Korean port records do not show who owned or sold the fuel.
Seoul’s response: no confirmed exports, legal action if laws broken
The foreign ministry said on Thursday that South Korea is strictly enforcing its export controls on Russia and stressed that no exports of commercial petroleum products to Russia have been confirmed through customs clearance procedures. In an explanatory note issued jointly by the industry ministry and the customs agency, it said the controlled items are determined through interagency discussions after considering their potential military use, economic impact and international coordination.
The ministry also made clear that commercial petroleum products are not subject to South Korea’s export controls on Russia, meaning that loading such products at South Korean ports does not in itself constitute a violation of domestic law. The government said it continues to monitor implementation of its export controls and, where necessary, takes action in accordance with the relevant laws and regulations. The presidential office separately rejected claims by Ukraine’s sanctions-policy adviser that the shipments had eased Russia’s fuel shortages.
The government indicated it would scrutinise the actual routes taken by the tankers and any deviations from their declared destinations. Officials noted that a vessel not proceeding directly to its declared destination is not, on its own, sufficient grounds to suspect a false declaration, but said the review would inform the final judgment on whether any laws were broken.

The three sanctioned tankers
| Tanker | Fuel loaded | Declared destination | Actual destination |
|---|---|---|---|
| Layla | ~57,000 tonnes of diesel (two trips, 19 July and 10 August) | Vladivostok, then Niigata, Japan | Vladivostok |
| Astoria | ~11,000 tonnes (Ulsan, 1 August) | Japan | Vladivostok |
| Chongchon | ~26,000 tonnes via ship-to-ship transfer off Yeosu | Singapore | Vladivostok |
Why the shipments matter
The shipments began precisely when Ukrainian long-range drone strikes on Russian oil refineries were cutting processing volumes and creating a fuel shortage inside Russia. Moscow has since imposed a ban on diesel and gasoline exports and restricted fuel purchases in some hard-hit regions. Ukraine’s sanctions-policy adviser Vladyslav Vlasiuk said the South Korean supplies helped Russia offset the loss of its own refining capacity — a claim Seoul’s presidential office rejected.
An analyst at the Centre for Research on Energy and Clean Air (CREA), Isaac Levi, called it “shocking that EU-sanctioned tankers loaded fuel at South Korean ports and carried it to Russia”, adding that it “undermines the sanctions regime and South Korea’s support for Ukraine”. Seoul has sent Ukraine humanitarian aid and non-lethal military supplies such as helmets, body armour and demining vehicles, and in 2023 pledged US$2.3 billion in support, most of it in loans — but it has long ruled out directly supplying weapons to Ukraine.
Conclusion
South Korea’s position sits between the letter of its own law and the expectations of its Western partners: refined petroleum products fall outside its Russia export controls, so the loadings do not automatically breach domestic law — yet sanctioned tankers sailing from its ports to Vladivostok raise questions Seoul can no longer leave unanswered. The government’s monitoring review, and any legal action that follows if violations are confirmed, will be closely watched in Kyiv, Brussels and London.
