A row over the end of Russian gas flows via Ukraine has intensified as Hungarian Prime Minister Viktor Orban threatened to block the next rollover of EU sanctions against Russia unless Brussels helps to achieve a restart of supply.

Hungarian Foreign Minister Péter Szijjártó, following Prime Minister Viktor Orbán, has declared that Budapest will block the next extension of EU sanctions against Russia unless Ukraine "refrains from measures that harm Hungary’s energy security".

Hungary wants the European Union to intervene in a gas dispute it has with Ukraine, a potential sign of friction in the bloc’s upcoming discussions over renewing sanctions against Russia.

Hungarian Prime Minister Viktor Orban threatened on Friday to block the next rollover of EU sanctions against Russia unless Brussels helps achieve a restart of Russian gas transit via Ukraine, which was halted on Jan.

Hungary has not yet decided whether to support the sanctions rollover due at the end of this month. The EU renews sanctions every six months and requires unanimity among its 27 member countries to do so.

The European Union will moved forward with a renewal on Russian sanctions after a deal was struck with Hungary, according to multiple reports.

The European Union (EU) has been placing sanctions on Russia since the beginning of the full-scale war in Ukraine. These sanctions are meant to pressure Russia into stopping its attacks. However, the EU can only continue these sanctions if every country in the group agrees.
