Moscow's suspension of gas for Austria, the main receiver of gas via Ukraine, means Russia will now only supply significant gas volumes to Hungary and Slovakia, in Hungary's case via a pipeline running mostly through Turkey. In contrast, Russia met 40% of the European Union's gas needs before Moscow's 2022 invasion of Ukraine.

Russian gas exports through Ukraine to Europe - the main transit route for the gas to the EU - were stable on Monday, according to Kremlin-controlled energy company Gazprom , despite the company cutting off gas supplies to Austria's OMV .

Austrian utility OMV says supplies from Russia’s state-owned natural gas company Gazprom stopped early Saturday after the company said it would stop payments for the gas following an arbitration award.
