Bulgaria threatens 21st Russia sanctions veto

The EU's 21st sanctions package against Russia is being assembled around the shadow oil fleet, Russian banks and the Russian Orthodox Church (Hromadske, S&P Global). In Sofia, politicians are arguing over whether Bulgaria should block parts of it to shield Patriarch Kirill and interests linked to Lukoil. The fight matters because one national objection can stall sanctions for all 27 member states.

That weakness is not accidental. It is written into the treaties.

How one government stops the rest

EU sanctions fall under the Common Foreign and Security Policy, the part of the EU system where member states kept foreign policy in national hands instead of transferring it fully to Brussels. Article 31 of the Treaty on European Union makes unanimity the default. Every government must agree, or the decision does not pass (Council sanctions explainer).

The procedure has two stages. First, governments agree a political decision setting out who is being sanctioned and why, under Article 29 TEU. Then a separate regulation, under Article 215 TFEU, turns that decision into binding economic restrictions for banks and companies across the single market (Verfassungsblog).

The veto sits at the first stage. If one capital refuses the political decision, the economic machinery cannot start. The other 26 cannot simply outvote the holdout as they can on many internal-market laws.

For a small member state like Malta, this is a familiar EU bargain. National control protects sovereignty. It also allows one government, when a domestic interest is concentrated enough, to make everyone else choose between watering down the package and losing it altogether.

Hungary proved it works

Budapest showed how effective the tactic could be in 2022. Hungary demanded that Russian Orthodox Patriarch Kirill be removed from the EU's sixth sanctions package. The EU accepted the demand and dropped Kirill to preserve the wider deal (Reuters, Politico).

Hungary did not need to convince the rest of the EU that Kirill deserved protection. It only had to make the cost of keeping his name on the list higher than the cost of removing it.

That lesson has travelled. Bulgaria's president threatened in 2023 to veto sanctions on Russia's nuclear sector (Reuters). Bulgarian political actors are now seeking changes to the 21st package linked to Kirill and to Lukoil, which operates Bulgaria's largest refinery in Burgas (S&P Global). That refinery is central to Bulgaria's fuel supply, giving Sofia leverage that goes beyond religious symbolism.

There is no public evidence that Hungary is coordinating Bulgaria's current position (Council Russia sanctions page). The more important point is that coordination is not necessary. Once one government proves that a single-name objection can reshape a sanctions package, every capital with a sensitive domestic exposure understands the method.

The motives vary: energy dependency, refinery exposure, religious ties. The leverage is the same. Hungary and Slovakia secured pipeline exceptions during the sixth sanctions package by pointing to their landlocked energy supply (Council sixth package). They also delayed the 20th package earlier this year during a dispute with Ukraine, before lifting their vetoes in April (The Geopost).

No organised bloc is required. The unanimity rule supplies the leverage by itself.

What remains unclear

The open question is the formal status of Bulgaria's demand. The treaty mechanics are clear, and the Hungary precedent is well established. What no public Council document confirms is whether Sofia has formally requested removals from the draft annex of the 21st package.

The political clash in Bulgaria has been reported in domestic media. Council negotiations remain closed. Whether this becomes an actual blockage or stays as a pre-negotiation signal depends on what Sofia does when diplomats put the final text on the table.

After 20 sanctions packages (Council Russia sanctions page), the EU has built substantial economic pressure against Russia. But each new round still has to pass through the same unanimity lock.

That lock reflects a deliberate treaty choice: foreign policy remains under national control. The cost, however, keeps accumulating. Each time the other 26 accommodate a narrow objection to save a package, the next capital learns that the tactic is available, and that the EU is likely to pay the price rather than let the whole deal collapse.
