Co-Chair of the OSCE Minsk Group James Warlick commented on the presence of Armenian and Azerbaijani leaders at NATO summit in Wales. 

“The Presidents of Armenia and Azerbaijan are attending today's NATO Summit, a strong statement about our shared values and goals,” he tweeted.

Earlier Warlick said he would also attend the summit in Wales. In his recent interview he said there is an opportunity for the Armenian and the Azerbaijani presidents to come together either at the NATO summit, or on the margins of the UN General Assembly.
