No deal has been reached in Brussels between Ukraine and Russia on price for future gas deliveries, Ukrainian Energy Minister Yuriy Prodan said.

The talks between the two countries' energy ministers and the EU Energy Commissioner lasted for seven hours but the Ukrainian minister Yuriy Prodan said that no steps forward had been made since they last met a week ago.

Moscow threatened to cut off gas supplies to Ukraine on June 10 if Kyiv didn't pay, still the parties agreed to meet again either on June 10 or 11 in Brussels, RFE/RL reports.

The structure for debt payment is close to being agreed, but that the gap in the gas price, with Kyiv insisting on a price of $268.50 per 1,000 cubic meters and Russia stands by its demand for $485.

Meanwhile Bulgaria has suspended all activities related to Russian-backed South Stream gas pipeline project until it reaches agreement with the EU on it.
