France Targets Tagor Captain

A French Navy warship followed the Tagor for days across the Atlantic before boarding it west of Brittany. The tanker had changed flag during the voyage, from Madagascar to Cameroon, but both registrations were invalid. Its Russian captain refused orders (Maritime Executive). A British warship helped track the vessel overnight (NDTV).

The Tagor is now in Douarnenez Bay under criminal investigation for défaut de pavillon, sailing without a valid flag. France has seized shadow fleet tankers before, but this is the first case to move into criminal prosecution rather than an administrative fine (Euronews). President Emmanuel Macron called sanctions evasion "unacceptable" (DW). Paris is testing whether interception at sea can become a legal weapon, not just a political message.

One Country Moves While 27 Cannot Agree

France is using UNCLOS, the United Nations Convention on the Law of the Sea, the treaty that sets the basic rules for maritime rights. Article 110 allows warships to stop vessels on the high seas if they have no valid flag (Völkerrechtsblog). That route avoids the EU’s main problem: sanctions changes require unanimity, so all 27 member states must agree.

The EU’s 21st sanctions package, expected in early June, will add more shadow fleet tankers to the target list (Livemint). But the Full Maritime Service Ban, which would stop EU companies from insuring, crewing or servicing vessels carrying Russian oil, remains blocked. According to Euronews Greece, Greece and Malta say such a ban can only happen if the G7, the group of major Western economies, moves first. Cyprus took the same line during negotiations on the 20th package.

That is where the Malta angle sits. Greek, Cypriot and Maltese companies earn billions from maritime services linked to vessels carrying Russian cargo. The governments resisting the strongest ban are not doing so in the abstract. They are defending sectors that still make money from the trade the sanctions regime is trying to squeeze.

Poland leads the other side. Seven member states have demanded tougher shadow fleet restrictions (Newsmax Polska). Poland and Denmark have held joint exercises practising how to board suspected shadow fleet vessels (PolSOF). The fight is now between member states prepared to use the tools they already have and member states that fear the economic cost of letting those tools bite.

The Baltic Standoff

Even the tougher camp has limits. Estonia’s foreign minister praised France’s boarding as "the right signal" (ERR). But Estonia has also acknowledged that boarding tankers in the Baltic is far riskier. Russian escort vessels shadow the ships and make enforcement dangerous at the point where it would have to happen. Denmark controls the only chokepoints into the Baltic, the Danish Straits, and has carried out no boardings.

France can act in the open Atlantic because Russian naval escorts are not present there. In the Baltic, where shadow fleet traffic is thickest, proximity to Russian bases changes the calculation. Enforcement is happening where it is safest, rather than where the pressure is most needed.

Russia is adjusting. It has been systematically reflagging shadow fleet vessels under its own registry (Ukrainska Pravda). Once a vessel carries a valid Russian flag, it is no longer stateless and cannot be boarded under UNCLOS Article 110. If Moscow completes that re-registration campaign, the legal route France used against the Tagor closes. The alternative would require UN Security Council authorisation, which Russia would veto.

The Tagor remains in a French bay, with its captain facing criminal charges. Ship by ship, Russia is closing the loophole that allowed France to board it.
