Russian gas deliveries have also been resumed to Hungary, Slovakia and Austria.
Following Sunday's talks between the two country's premiers, Russian energy giant Gazprom and Ukrainian energy company Naftogaz signed on Monday a contract on Russian gas supplies to Ukraine for 2009-2019. Gazprom CEO Alexei Miller said Ukraine would pay $360 for 1,000 cu m of Russian gas in the first quarter of 2009.
Russia suspended supplies to Ukraine on January 1 after the former Soviet neighbors failed to reach an agreement on a new gas contract for 2009. A week later, Gazprom cut off gas deliveries to the European Union, saying Ukraine was stealing gas intended for EU consumers.
Around 20 European countries were affected by the dispute, with the EU calling the disruption to supplies "completely unacceptable."
Bulgaria is a key transit country of Russian gas to the Balkans. According to the EU, Bulgaria suffered to a greater extent over the gas supply stoppages than any other European Union member state.
The economics and energy ministry also said Bulgaria was waiting for sufficient amounts of gas to start transit to Balkan countries.
