Russia and United States can continue to work on peace in Nagorno-Karabakh, Co-Chair of the OSCE Minsk Group James Warlick said.

“While the US cannot accept #Russia's actions in #Ukraine, there are areas where can continue to work together - peace in Nagorno-#Karabakh,” he tweeted.

Besides, he believes they should consider “what is to be learned from events in #Ukraine for conflict in #Armenia and #Azerbaijan” .
