BRUSSELS, April 17 – Expert-level talks between Russia, Ukraine and the European Commission made progress toward resolving differences over Russian gas supplies to Ukraine, but no date has yet been set for a high-level meeting, the European Commission said on Friday.

"There was a trilateral technical meeting in Brussels yesterday afternoon where all the parties met at the civil servant level to discuss the remaining open issues which include the pricing of gas, as well as the amounts of gas and financial support to Ukraine," Commission spokeswoman Anna-Kaisa Itkonen told the Commission's daily news briefing.
