The Nagorno Karabakh conflict may be discussed on the sidelines of NATO's 2016 Warsaw Summit, a U.S. diplomat said Thursday, July 7.

“Just arrived in Warsaw for the NATO summit,” the U.S. Co-chair of the OSCE Minsk Group, Ambassador James Warlick tweeted.

“It's an opportunity to continue discussions on the Nagorno Karabakh peace with Armenia and Azerbaijan.”

Armenian President Serzh Sargsyan and Azeri leader Ilham Aliyev met on June 20 in Saint Petersburg to address the conflict, with Russian President Vladimir Putin mediating the talks. The Armenian and Azerbaijani presidents confirmed their commitment to the implementation of agreements reached at a Vienna-hosted meeting on May 16. To that end, they have agreed to increase the number of international observers in the Nagorno Karabakh conflict zone. Also, they expressed satisfaction that the ceasefire was now holding.

Prior to that, a meeting between both leaders was organized on May 16 in Vienna, with top diplomats from the MG co-chairing countries hosting the summit.
