Slovakia's Robert Fico has slammed Brussels' planned phase-out of Russian energy as an ideological decision and a threat to sovereignty

Slovakia is "ready to fight" for its right to import Russian gas and will continue to block Brussels' proposals to phase out Russian energy, Prime Minister Robert Fico said on Saturday.

Fico stressed that energy security is a strategic priority for Slovakia, and that EU efforts to change its supply mix threaten national sovereignty.

Slovakia vetoed the EU's 18th round of sanctions on Russia for the second time on Friday, citing concerns over the RePowerEU plan, which seeks to cut Russian energy imports by 2028. The plan is being discussed alongside sanctions targeting Russia's energy and financial sectors.

Brussels is seeking to pass the phase-out as trade legislation - requiring only a qualified majority. Fico insists, however, that the plan amounts to sanctions and must be unanimously approved. He previously warned that the move could jeopardize energy security, raise prices, and trigger costly arbitration with Gazprom over Slovakia's long-term energy contract.

Speaking during celebrations for Slovakia's Saints Cyril and Methodius Day, Fico called the phase-out plan a "disruption" of Slovakia's national interests.

"We refuse to support another sanctions package against the Russian Federation, unless we know who will protect us, and how, and compensate for the damage that will be caused to Slovakia by the ideological proposal of the European Commission to stop supplies of Russian gas," he said.

"Slovakia wants to be sovereign and self-determined. And we must answer whether we are ready to fight for it. I am ready to fight this difficult battle. We are going to get through it."

Fico added that vetoing the phase-out means "fighting for our households and businesses" so they won't bear the costs of "harmful ideological decisions" from Brussels.

He went on to say that Slovakia is at a crossroads - between giving in to pressure from "bureaucratic structures" in Brussels and defending its interests. He urged the public to choose the latter and accused the EU of ignoring national interests and violating international law by forcing harmful policies onto member states. Fico argued that Slovakia must pursue cooperation "based on equality and mutual benefit," not external political agendas.

Hungary has also blocked the Russian energy phase-out plan, with Foreign Minister Peter Szijjarto warning that it would "destroy Hungary's energy security" and cause price spikes.

Moscow has condemned the Western sanctions as illegal and counterproductive, particularly those targeting energy, noting that energy prices in the EU surged after the initial sanctions on Russia were introduced in 2022. Russian officials warn that the EU's rejection of Russian supplies will push it toward more expensive imports or rerouted Russian energy via intermediaries.
