Slovakian Prime Minister Robert Fico railed on Thursday against Ukraine's decision to cut off the transit of Russian gas to the European Union, repeating his warnings of possible retaliation against Kiev.

Fico said that Slovakia could halt its humanitarian aid to Ukraine, cut or cancel social benefits for Ukrainian refugees, and cease emergency electricity supplies to Ukraine. He also suggested using veto power over EU decisions as leverage against Kyiv.

A meeting between Slovak, Ukrainian and European Commission officials over gas supplies planned for Tuesday has been cancelled because Kyiv will not participate, Slovakia said on Monday.

Slovakia’s Prime Minister Robert Fico said he wasn’t ruling out the resumption of gas through Ukraine after a deal between Kyiv and Moscow expired at the beginning of this year.

Slovakia is considering retaliatory measures against Ukraine, including withholding aid, unless a resolution is reached regarding Kyiv's decision

Slovakia may halt humanitarian aid and emergency electricity supplies to Ukraine and leverage its veto power in EU matters should Kyiv not resume gas flows through its territory, Prime Minister Robert Fico said in Brussels today.

Poland is prepared to step up electricity exports to Ukraine if Slovakia’s Prime Minister Robert Fico follows through on his threat to cut off back-up power supplies to the war-torn country, a senior official said on Sunday.

Slovakia has criticised Ukraine's decision to end Russian gas transit to Europe, calling it a costly blow not only to Slovakia but the entire EU. While some member states downplay the impact, others face mounting pressure over energy security amid winter demands.

Russian President Vladimir Putin promised Slovakia that Russia's Gazprom would find alternative ways to deliver contracted gas to Slovakia after the end of transit through Ukraine, Slovak Prime Minister Robert Fico said on Friday.

Slovakian Prime Minister Robert Fico said Russia will if necessary deliver gas to cover the country’s domestic consumption this year, even as he seeks to restore fuel flows via Ukraine.
