Supplies of Russian gas are flowing to Ukraine after a six-month suspension.
Maksim Belyavskiy, the head of Ukraine's gas transportation network Ukrtransgaz, said on December 9 that gas supplies from Russia to his country have resumed.
Belyavskiy said Ukraine should receive some 43.5 million cubic meters of gas daily for the rest of this month.
State-controlled Russian exporter Gazprom confirmed it resumed deliveries to Ukraine after received a $378 million prepayment for 1 billion cubic meters of gas for December.
Russia suspended gas shipments to Ukraine in June as tension mounted following the ouster of Ukranian President Viktor Yanukovych and Moscow's annexation of Crimea.
Gazprom cited Ukraine's multi-billion dollar gas debt and demanded prepayment for future supplies.
The resumption of supplies follows an October 30 deal signed by Russia, Ukraine, and the EU to ensure deliveries to Ukraine over the winter.
