Azeri Foreign Minister Elmar Mammadyarov is satisfied with Russia's mediation in the Nagorno Karabakh conflict settlement. "Russia's role in the settlement process became constructive. Generally, Russian diplomats carry out a great deal of work and assist in the process," Mammadyarov said. He also marked out Russia's positive role in the Prague process, which determined 8-9 main principles of the conflict settlement. "Many of them have been already coordinated. There are 1-2 questions left," the Azeri FM said, reports Interfax.
