The French court sentenced Chinese tanker captain Zhangjie Chen to one year in prison in absentia, underscoring a growing European resolve to curb Russia’s “shadow fleet.” Chen, 39, was convicted after French special forces boarded the un‑flagged vessel **Boracay** off Saint‑Nazaire in September 2025, where the ship was found carrying roughly $100 million of Russian oil from Primorsk. The ruling highlights Paris’s determination to enforce sanctions that aim to block Moscow’s use of aging tankers to evade the oil embargo imposed after its invasion of Ukraine Politico.
EU widens sanctions to choke the shadow‑fleet network
France’s action follows a broader EU initiative that introduced a fresh sanctions package targeting maritime services for vessels linked to Russia’s covert shipping network. The package, approved in March 2024, seeks to deny shadow‑fleet ships access to insurance, crew contracts and port facilities, making illicit operations costlier and riskier Reuters. While the EU has already barred hundreds of suspect tankers from its ports, enforcement remains uneven, with some member states—most notably Hungary—blocking tighter measures.
Legal complexities and diplomatic push‑back
Chen’s defence lawyer, Henri de Richemont, argued that the boarding violated French jurisdiction because the Boracay was intercepted in international waters. The lawyer also cited the 2023 Helsinki ruling that dismissed charges against the Russian‑linked tanker Eagle S for alleged undersea‑cable sabotage, underscoring uncertainties over the legal basis for such prosecutions. Despite the appeal, the sentence represents the maximum penalty under French law for non‑compliance with boarding orders, coupled with a €150 000 fine.
Implications for European maritime security
High‑profile interdictions like the Boracay illustrate the limited reach of European naval assets. As senior fellow Charlie Edwards of the International Institute for Strategic Studies notes, “Few European capitals can sustain a high‑tempo posture for long, leaving random boardings looking potentially escalatory without being strategically decisive.” Nonetheless, the combined French prosecution and EU sanctions signal a coordinated effort to pressure the Kremlin into re‑flagging or abandoning the shadow‑fleet model, even as Russia adapts by deploying military escorts for vulnerable vessels.
The case serves as a warning to operators that even absent‑in‑person arrests, European courts are prepared to impose criminal sanctions on captains and companies that facilitate sanctioned oil flows, reinforcing a broader strategy to choke the financial lifelines of Russia’s illicit maritime network.
