It’s a notable evolution in strategy for the EU, and came after Germany and Hungary held up a deal for weeks.

The EU will hit Russia with unprecedented sanctions against its lucrative gas sector, according to the Belgian EU presidency — a once-unthinkable step that could drain hundreds of millions from Moscow’s war chest.

The decision, which EU ambassadors reached Thursday morning, came after stiff opposition from Germany and Hungary stalled a deal for weeks — though over different parts of the package.

The penalties won’t hit the majority of Russia’s liquid natural gas (LNG) exports to the EU. Instead, they will ban EU ports from reselling Russian LNG after it arrives and block financing for Russia’s planned Arctic and Baltic LNG terminals.
