Both Russia and Hungary have hit back, however, warning Kyiv not to meddle in the bilateral agreement.
Peter Szijjarto, Hungary’s Foreign Minister, said on Tuesday Ukraine’s ambassador was summoned in response to the country’s objections to the deal.
He said: “We regard it a violation of our sovereignty that Ukraine wants to block a secure gas supply for Hungary.”
According to Ukraine, the 15-year deal between Budapest and the Kremlin is a “purely political, economically unreasonable decision”.
Kyiv said it will ask the European Commission to determine whether it was in line with European energy law.
Mr Szijjarto went on to say he was “outraged” by the news.
