The European Union’s latest sanctions package against Russia is being presented in Brussels as further proof that the bloc remains united in keeping economic pressure on the Kremlin. But the debate around the measures also shows that Europe’s energy strategy still faces clear limits.

Greece has emerged as a key example of that tension. The country’s position highlights how difficult it is for the EU to impose tougher energy-related restrictions while also protecting member states with major exposure to shipping, fuel trading, and wider market disruptions.

Since February 2022, sanctions have been one of Europe’s main tools in response to Russia’s war. Yet every new round appears to bring the same challenge: political resolve may be strong, but the practical impact on oil flows, transport networks, and energy costs makes enforcement more complicated.

That leaves the EU balancing two goals that do not always move easily together — maintaining pressure on Russia and preserving stability inside Europe’s own energy system. Greece’s role in the latest discussions underlines that future sanctions may be shaped as much by market realities as by political messaging.
