Sergei Kupriyanov, a spokesman for Russia’s Gazprom, says talks in Kyiv about its gas dispute with Ukraine ended early on June 15 without any breakthrough.
Kupriyanov said a new date for talks has not been set.
Earlier, Ukraine’s Energy Minister Yuriy Prodan said negotiations would continue on June 15 in a bid to resolve the dispute over Russia’s gas price.
Moscow is threatening to cut supplies to Ukraine if Kyiv does not pay $1.95 billion by June 16.
The move would cut deliveries passing through Ukraine to the European Union – which was represented in the talks by European Energy Commissioner Guenther Oettinger.
Ukraine has offered to pay debts to Gazprom if Moscow agrees to charge $326 per 1,000 cubic meters of gas for 18 months.
Russia says its "final price" is $385 per 1,000 cubic meters.
