Péter Szijjártó, Minister of Foreign Affairs and Trade, said next week's meeting of the European Union's Energy Council is expected to see a "big battle".
In a Facebook post, the foreign minister said the Hungarian government "will not allow Brussels to take the money needed to extend the war in Ukraine from Hungarian families."
Minister Szijjártó said that the council meeting in Luxembourg on Monday is scheduled to table "a Von der Leyen-Zelensky proposal aiming to force us to stop buying natural gas, crude oil and nuclear fuel from Russia."
Minister Szijjártó said: "Brussels wants to support Ukraine by doubling or tripling the utility costs of Hungarian families."
Minister Szijjártó said he had talked to his Slovak counterpart, Juraj Blanar, and they had agreed that "such a gross violation of sovereignty is unacceptable."
"The national energy mix is a matter of sovereignty that no outside player can interfere with. We are not willing to replace our already existing energy resources with more expensive and more unstable ones, not for the sake of Brussels or Kyiv," Minister Szijjártó said.
He pledged that the government would "protect Hungarian families from having to pay two or three times the current utility fees because of the blackmail of [Ukrainian] President [Volodymyr] Zelensky!"
