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.

Hungarian Prime Minister Viktor Orban called on the European Union to pressure Ukraine to re-establish the transit of Russian gas to Europe, and linked the issue to extending sanctions against Moscow.

Hungary's representatives have not yet agreed to a decision on the extension of EU sanctions against Russia. The issue will be considered at an EU Council meeting at foreign minister level on Monday,

The fate of the European Union’s sanctions against Russia were thrown into limbo after a top Hungarian official called for a “debate” and signaled their renewal by the end of the month shouldn’t be automatic.
