Putin Calls EU Ship Seizures ‘Piracy,’ Vows Retaliation

Russian President Vladimir Putin has condemned the European Union’s plans to seize Russian commercial vessels as “piracy and robbery,” warning that Moscow will respond “in kind” if European countries carry out the measures. The statement, delivered Wednesday during a visit to Pacific Fleet exercises near Sakhalin Island, marks a significant escalation in the maritime standoff between Russia and the EU over sanctions enforcement.

“We see that the authorities of some countries, in violation of international maritime law, are trying to restrict the movement of our economic operators’ vessels, which are peaceful, I want to stress,” Putin said, according to The Moscow Times. “And recently they came up with the idea of seizing our vessels and selling off the looted property. This is, of course, nothing other than piracy and robbery.”

The EU’s 21st Sanctions Package

The warning follows the European Union’s adoption in July of its 21st sanctions package, which introduced a mechanism allowing member states to confiscate and sell Russian oil and other cargo carried aboard shadow fleet vessels attempting to evade the bloc’s sanctions. The measure also covers grain cargoes, as Meduza reported.

The “shadow fleet” refers to aging, often uninsured vessels registered in third countries with lax regulations — so-called flags of convenience — that Russia uses to transport oil and other sanctioned goods while evading Western sanctions. As of May 2026, a Ukrainian government register had identified 1,404 vessels belonging to Russia’s shadow fleet, according to The Kyiv Independent.

Putin’s Warning and the Pacific Fleet

Speaking aboard the missile cruiser Varyag during the final stage of Pacific Fleet exercises in Yuzhno-Sakhalinsk, Putin said Russia’s response would not necessarily be confined to the waters where Russian ships were seized.

“We will not necessarily act in the waters where raids on our ships and vessels are being planned, but wherever we ourselves consider it necessary and appropriate,” he said, as reported by Al Jazeera. “Anywhere, including in the Pacific Fleet’s area of responsibility.”

Putin said he had already given instructions to the Russian Defense Ministry to prepare a response.

Pacific Fleet Commander Viktor Liina then reported that Russia has “forces for inspection and detention of ships of unfriendly states and their shadow fleet.” He said 1,001 vessels passed through Russia’s exclusive economic zone along the Kuril Islands between April 24 and August 6, 2026, including 379 under flags of “unfriendly” countries — 273 dry bulk carriers and 71 tankers. Twenty-six were British and nine were French.

“We know the routes, what they are carrying and whose ships they are,” Liina said, according to Kommersant.

Medvedev’s Hardline Position

Deputy Chairman of Russia’s Security Council Dmitry Medvedev went further, asserting that Russia has the “right to attack any commercial vessel of enemy countries” in both Russian and neutral waters if there are sufficient suspicions it is carrying cargo in the interests of the adversary.

“Of course, European dogs have no rights to detain such vessels, neither in accordance with the 1982 Convention on the Law of the Sea, nor in accordance with national legislation,” Medvedev wrote, as reported by Gazeta.ru. “Our Armed Forces are capable of sharply expanding work beyond the Black Sea basin!”

European Maritime Enforcement Campaign

EU countries and Britain have detained five tankers carrying Russian oil since the start of 2026. The MV South Star was stopped on July 20 in an operation involving EU countries. France intercepted the tankers Grinch, Deyna and Tagor before later releasing them, while Britain has held the Smyrtos — carrying 100,000 metric tons of oil — since June 14.

In a landmark case, Sweden’s Supreme Court ruled on August 4-5 that the cargo ship Caffa should be handed over to Ukraine. The ship was seized in March 2026 off Trelleborg, Sweden, while flying a false Guinean flag, and was suspected of transporting grain from Russian-occupied Ukrainian territory. It is the first time a court has ordered a Russian ship suspected of transporting stolen Ukrainian grain to be transferred to Kyiv, according to Euronews.

Ukrainian Foreign Minister Andrii Sybiha welcomed the decision, saying it “sets an important precedent, demonstrating that decisive action by law enforcement and prosecutors, combined with an independent and impartial judiciary, can translate the principle of accountability into tangible results.”

Escalation Risks and Geopolitical Context

Putin’s threat to respond “anywhere” — not just in the waters where Russian ships are seized — dramatically broadens the potential scope of confrontation. The detailed reporting by the Pacific Fleet Commander on maritime traffic in the Kuril Islands region suggests Russia is actively monitoring potential targets, as Business Insider noted.

Putin also accused NATO of making inroads into the Asia-Pacific region and heightening tension in the Arctic. The Russian naval exercises in the West Pacific come a week before joint US-South Korean war games designed to simulate a possible invasion from North Korea.

The dispute occurs against the backdrop of Russia’s ongoing full-scale invasion of Ukraine since February 2022, Western sanctions aimed at crippling Russia’s energy revenues, and Ukraine’s campaign of attacks on Russian energy infrastructure and shadow fleet vessels in the Black Sea.

What to Watch For

The central question is whether Russia will actually follow through on its threat to seize European vessels, or whether this is primarily rhetorical posturing. European countries have significantly increased coordination on shadow fleet enforcement, with multiple nations conducting interceptions and the EU expanding naval operations (IRINI and Atalanta) to target shadow fleet vessels.

As Xinhua News reported, Putin has previously called the seizure of Russian vessels “piracy” — first in late July, when he urged the commanders of the Pacific and Northern fleets to “act carefully” within the framework of international maritime law, “but decisively, the way piracy and pirates need to be fought.”

The coming weeks will reveal whether Putin’s latest warning translates into concrete action, and how the EU responds to any Russian retaliation. The potential for direct naval confrontations, expanded sanctions, and broader impacts on global shipping routes remains high.
