OSCE Minsk Group on Karabakh conflict resolution is working effectively, the U.S. and France co-chairs Robert Bradtke and Bernard Fassier said on Wednesday speaking at the hearings of European Parliament Foreign Affairs Committee on Nagorno-Karabakh conflict settlement.

“We consider the version of basic principles that is currently on the table fair and balanced. We would like to see the sides adopt it at forthcoming meeting in Kazan," said OSCE Minsk Group U.S. co-chair Robert Bradtke, stressing that the basic principles are not an agreement, they only outline the settlement.

"At various stages of negotiations, Armenia and Azerbaijan were against the presented principles, but during the last meeting in Sochi we have achieved certain progress, having received verbal consent of the parties. We hope that it will soon be endorsed in the form of text," Radio Liberty quotes Bernard Fassier.
