NEWPORT (UK), September 05./ITAR-TASS/. The Ukrainian crisis cannot be resolved without Russia's participation, the chairperson-in-office of the Organisation for Security and Cooperation in Europe said on Friday.

Didier Burkhalter highlighted Russia's role in returning stability to Ukraine and Europe as a whole speaking at the NATO summit in Wales.

He also said Russia's isolation will solve no existing problems but will create new ones in Europe and beyond.
