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.

Hungary wants the European Union to persuade Ukraine to resume gas transit from Russia to Europe, Prime Minister Viktor Orban said on Friday, signalling a tough debate as the EU seeks to extend its sanctions against Russia over the coming week.

Hungary prolonged its blockage of the renewal of sanctions against Russia as Prime Minister Viktor Orban called on the European Union to pressure Ukraine to re-establish the transit of Russian gas to Europe.

The European Union requires a unanimous vote to extend sanctions on Russia, a situation Hungary's Viktor Orban wants to use to pressure the bloc into forcing Ukraine to reopen a transit pipeline for Russian gas.

Hungarian Prime Minister Viktor Orban is making the extension of sanctions against Russia contingent on Ukraine fulfilling several conditions. Among these, he has mentioned the resumption of Russian gas transit through Ukrainian territory and ensuring the security of oil supplies.
