KIEV, April 4 - Ukraine has made progress in talks on the diversification of gas supplies to the country, First Deputy Prime Minister Valeriy Khoroshkovsky said.

"I can only confirm that these negotiations are being conducted. Partly, they're already successful, so we'll have other sources of gas supplies," he said in an interview with the BBC Ukrainian Service on Wednesday.

At the same time, he declined to say with what companies and countries gas supplies to Ukraine are being discussed, as well as the possible routes of gas shipments.
