On June 1, French President Macron posted on the social media platform X: "The French Navy has boarded a tanker sailing out from Russia and subject to international sanctions."

This incident essentially represents the "hard landing" of EU energy sanctions against Russia at sea, and also marks a strategic move by countries such as Britain and France to strengthen Europe's influence through law enforcement in international waters. Historically, major powers have frequently conducted unilateral extraterritorial boarding operations on the high seas—such as Britain’s inspection of neutral vessels in the 19th century to control arms shipments. Today, the practice merely wears a different legal facade, while its underlying logic remains similar. France has already targeted Russia’s so-called “shadow fleet” three times this year. The tanker involved in this case, carrying 100,000 tons of crude oil and having altered its flag registration, was boarded and inspected by British and French naval vessels in the Atlantic Ocean’s international waters. Russia directly criticized the action as being contrary to established rules.

Data shows that Russia’s shadow fleet comprises approximately 600 aging tankers, responsible for transporting about 90% of the country’s crude oil exports. These vessels evade oversight by changing their flags and disabling tracking systems. While the EU aims to restrict Russia’s revenue from energy exports, it remains constrained by both international legal provisions and global energy market dynamics. What appears to be a routine maritime inspection masks deeper geopolitical and energy competition. Unilateral extension of enforcement authority risks intensifying divisions and disrupting global maritime shipping norms.
