(VOVworld) - Russia and Ukraine resumed efforts Wednesday to resolve a gas pricing dispute after a Russian deadline for Kiev to pay some of its debts passed without Moscow cutting off supplies. Russia had given Ukraine until 0600 GMT on Tuesday to pay some of the billions of dollars it owes, but pulled back from the deadline after officials said talks brokered by the European Commission would continue. The eight-hour negotiation between Moscow and Kiev in Brussels, which ended around 0100 GMT on Tuesday, failed to overcome differences over pricing.
