The Russian Energy Ministry sent a proposal to the European Commission on October 3, saying that Ukraine should settle its gas debt for December 2013 worth $1.451 billion as a condition for new gas deliveries, he said.
According to Novak, Russia is ready to offer a more flexible schedule to Ukraine on condition that the whole sum is paid before the year end.
The next round of Russia-Ukraine-EU gas talks is scheduled to take place in Berlin Octover 21.
Russia stopped gas flows to Ukraine in June over an unsettled dispute over debt and gas prices. Russia said it is ready to resume natural gas supplies to Ukraine if Kiev repays its gas debt and makes advance payments for new gas deliveries.
The Naftogaz oil and gas company stopped paying for the consumed Russian natural gas on March 25. As of August 1, the overall debt of Naftogaz to Gazprom for supplied gas totaled about $5.3 billion.
