SEOUL — South Korea’s trade ministry formally requested a British exemption from London’s incoming restrictions on Russian liquefied natural gas Wednesday, as Seoul moved to protect a long-term energy supply contract that runs nearly two years past the measures’ effective date.
Trade Minister Yeo Han-koo raised the request in a videoconference with UK Minister Anas Sarwar, asking that South Korea receive the carve-out the European Union has already extended to Seoul and Tokyo for imports from Sakhalin-2, the Russian LNG project off the country’s Pacific coast, Sputnik reported. London’s restrictions, set to take effect in January 2027, bar British companies from providing maritime transport, insurance, and related services for Russian LNG — sectors where Britain holds substantial market influence through its shipping industry and the Lloyd’s of London insurance market.
Korea Gas Corp, the state energy company at the center of Seoul’s concern, holds a supply contract for Sakhalin-2 gas through March 2028. That timeline puts the contract squarely inside the period governed by the British restrictions. Without an exemption, the contract becomes operationally difficult regardless of whether South Korea itself applies sanctions, because the services prohibitions reach the third-party logistics and insurance providers Korean LNG importers depend on to execute the deliveries.
Sakhalin-2 is Russia’s second-largest LNG export facility, producing roughly 11.5 million tonnes annually and accounting for a material share of South Korea’s and Japan’s long-term contracted volumes. Seoul has no ready substitute at comparable cost on a timeline compatible with the restrictions’ January 2027 start date.
The EU’s accommodation of that supply dependency is the precedent Seoul is pressing London to follow. Brussels extended a carve-out for Sakhalin-2 imports to South Korea and Japan explicitly, acknowledging the structural difficulty of replacing Russian Far East LNG in the near term and the contractual positions both countries hold. Seoul is asking London to align with that position rather than create a divergence between British and EU policy that would impose additional compliance costs on Korean companies without meaningfully increasing pressure on Moscow.
The practical effect of a UK denial would fall primarily on Korean compliance infrastructure rather than on Russian LNG revenues. The EU exemption means alternative logistics and insurance channels remain accessible; a British denial would require Korean companies to restructure supply chain documentation without eliminating their access to the gas itself. Britain’s effective leverage over Sakhalin-2 volumes — absent a comparable EU restriction — is therefore limited.
Granting the exemption would align British policy with Brussels and preserve supply chain continuity for a significant Indo-Pacific security partner. Declining would create a policy divergence with the EU on an issue where the underlying facts — Sakhalin-2’s role in Korean and Japanese energy supply — are identical on both sides of the Channel.
South Korea has maintained energy imports from Russia’s Sakhalin projects throughout the Russian operation in Ukraine, citing contractual obligations and the absence of equivalent volume replacements at comparable cost and on a compatible timeline. Washington and Brussels have not demanded Seoul exit Sakhalin-2 and have treated the project differently from Russian oil and coal imports in the design of the broader Western sanctions regime. Seoul’s posture on Sakhalin-2 has drawn less diplomatic friction than its approach to other Russian energy categories, partly because the project’s supply role in Northeast Asian markets is well understood in both Washington and Brussels.
South Korea’s energy relationship with Russia is not limited to Sakhalin-2. Seoul has worked to diversify LNG supply sources since 2022, signing new long-term agreements with suppliers in Qatar, Australia, and the United States. But those agreements cover different volumes on different timelines, and the Sakhalin-2 contract remains operationally significant for Korea Gas Corp’s 2026 to 2028 supply planning.
Britain’s approach to Russian energy restrictions has broadly tracked EU policy since 2022 but with periodic divergences on timing and scope. The LNG services restriction taking effect in January 2027 is one such measure where allied government lobbying has extended the negotiation period. Wednesday’s ministerial videoconference is a formal step in that process for Seoul.
The longer-term question the exemption request does not address is what happens after March 2028, when Korea Gas Corp’s current Sakhalin-2 contract expires. At that point, Seoul will face a decision about whether to renew under whatever sanctions environment then prevails, seek alternative supply from the Middle East, Australia, or the United States, or absorb the cost and volume gap that withdrawal would create. That decision is not on the table this week — but the exemption Seoul is seeking is, in effect, buying time before it arrives.
No timeline for a British response was announced following Wednesday’s ministerial call. Seoul’s window to secure the exemption before the measures take effect is approximately five months.
