UK and EU Intensify Sanctions on Russia's Shadow Fleet to Disrupt War Funding

The UK said it is the first G7 country to sanction Russian liquefied natural gas (LNG) vessels recently acquired to service Arctic LNG-2, describing the project as a source of “dirty” revenue for the Kremlin; officials noted Arctic LNG-2 exported only about 1.3 million tons of LNG in 2025 despite capacity to export more than 13.5 million tons annually.
In addition to shadow-fleet targeting, the UK announced sanctions on a Russian military intelligence (GRU) network operating through a front company, LLC Neptune Co. Ltd., saying it identified 10 GRU members suspected of illicitly acquiring military technology needed to sustain Russia’s operations in Ukraine.
For the enforcement action, UK reporting specified that the Indian captain charged—Ajay Pant, 38—was arrested by the National Crime Agency (NCA) after a joint operation involving British armed forces, with prosecutors noting the seized tanker was MV Smyrtos; Pant was set to appear before a magistrate in Southampton, the case alleged breaches of UK sanctions involving supplying/transporting restricted Russian oil products to a third country, and the vessel reportedly remained anchored off Dorset with a crew of 24 (24 Indian and Georgian nationals). The Indian High Commission also sought consular access through the International Maritime Organisation (IMO).
The EU package included an entry ban: it imposed restrictions on former Russian military personnel involved in the aggression against Ukraine, and officials said work was ongoing to add individual sanctions for around 80 additional Russian companies and individuals.
The UK said its new round uses “enhanced powers” introduced last month and that it is targeting more than 20 shadow-fleet oil tankers under those authorities.
The UK announced sweeping new sanctions on Russia's shadow fleet of oil tankers on June 16, targeting more than 20 vessels under expanded legal powers introduced just last month. GOV.UK confirmed the package also covers four liquefied natural gas carriers linked to the Arctic LNG-2 project — making the UK the first G7 country to sanction Russian LNG vessels acquired for that scheme.
The announcement came one day after Indian ship captain Ajay Pant, 38, appeared in court on charges of violating UK sanctions while commanding the tanker MV Smyrtos through the English Channel. The vessel, seized by Royal Marine Commandos in a dramatic overnight boarding operation, now sits anchored off Dorset with 24 crew members still on board, The Guardian reported.
In the early hours of June 14, Royal Marine Commandos from 42 Commando fast-roped from RAF helicopters onto the deck of the MV Smyrtos as it carried 101,400 tonnes of Russian Urals crude oil through international waters, according to gCaptain. HMS Sutherland, HMS Ledbury, and an RAF P-8 Poseidon patrol aircraft supported the operation. It marks a sharp shift from paper sanctions toward physical enforcement on the high seas.
The legal basis for boarding was the ship's "stateless" status. Cameroon had quietly dropped the MV Smyrtos and 35 other Russia-linked vessels from its registry under EU pressure days earlier, gCaptain reported. Under Article 110 of the UN Convention on the Law of the Sea, stateless ships can be boarded in international waters. Captain Pant faces up to 10 years in prison. His case was referred to Bournemouth Crown Court for a hearing on July 16, ITV News reported.
The new UK sanctions hit more than 20 shadow fleet oil tankers and four LNG vessels recently acquired to serve the Arctic LNG-2 project. GOV.UK said the project exported only about 1.3 million tons of LNG in 2025 — a fraction of its 13.5 million ton annual capacity. Officials called the revenues "dirty money" funding the Kremlin's war. The UK now has 600 vessels on its sanctions list in total, Ukrinform reported.
Defence Secretary Dan Jarvis said every barrel of illicit oil intercepted directly reduces Russia's ability to make drones and missiles, according to NDTV Profit. The new round uses "enhanced powers" introduced in May 2026 that allow the UK to target ship insurers and other maritime service firms that keep the shadow fleet running. Prime Minister Keir Starmer said the measures target "the vessels, the money, and the actors propping up Russia's war economy."
Beyond tankers, the UK sanctioned a Russian military intelligence network operating under the cover of LLC Neptune Co. Ltd. Ten GRU officers — dubbed the "Neptune Ten" — were named for covertly buying Western dual-use technology to sustain Russia's weapons production, Washington Times reported. Named individuals include Stanislav Sergeyevich Popov, identified as the director of Neptune, and Ruslan Petrovich Koshkin.
The EU added 81 new listings — 34 individuals and 47 entities — to its Russia sanctions list this week, targeting Moscow's military-industrial complex, hybrid networks, and shadow fleet, according to the EU Council. The bloc also extended sanctions tied to the illegal annexation of Crimea and Sevastopol until at least June 23, 2027. EU High Representative Kaja Kallas said the measures "strike at the heart of Russia's military-industrial complex."
The arrest of Captain Pant triggered a diplomatic response. The Indian High Commission sought urgent consular access for Pant and the 12 Indian crew members aboard the Smyrtos through the International Maritime Organisation, The Hindu reported. India's media largely framed Pant as an employee caught between his corporate employer — Hong Kong-based Zhao Yao Shipping — and a geopolitical clash between Russia and the West. The case has sent a stark warning to mariners worldwide: operating a shadow fleet vessel is now a criminal risk, not just a corporate one.
