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.

Long reputed to be Russia-friendly, Hungarian Prime Minister Viktor Orban has often railed against the continuation of the EU sanctions, claiming that they impose an intolerable burden on the Hungarian economy and provide no solution for the carnage in Ukraine.

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.
