A strong will demonstrated by the presidents in the settlement of Nagorno Karabakh conflict created deep impression, the U.S. co-chair of the OSCE Minsk Group Robert Bradtke said, APA reports quoting ArmToday.

“I think today was impressive the way, that two presidents worked with us, their willingness to discuss the points that are quite difficult and quite controversial and I think, as someone who is relatively new to this process, that is what impressed me the most,” he said.

The negotiations between the presidents of Azerbaijan and Armenia were held on November 22 in Munich, Germany.
