WASHINGTON. - U.S. are disappointed with the results of Armenian, Azerbaijani and Russian Presidents’ meeting in Kazan, Spokesperson for U.S. State Department Victoria Nuland told a press briefing on Monday.

“The presidents of Armenia and Azerbaijan were not able to agree on the basic principles when they met in Kazan. However, in their joint statement with President Medvedev, both of them noted that they had improved their understanding on a number of issues, agreed to keep working on the basic principles, and to come back together at a future date to be specified. But I would say it’s disappointing,” Nuland said, U.S. State Department reports.

Earlier, Armenian News-NEWS.am reported that at the end of the meeting of Armenian, Azerbaijani and Russian Presidents in Kazan parties released joint statement that said:

“Presidents of Armenia, Azerbaijan and the Russian Federation met on June 24, 2011 in Kazan and reviewed work carried out under their instruction to agree on draft basic principles of the Nagorno-Karabakh settlement. Heads of the states noted the achievement of mutual understanding on a number of issues. Solution of these issues contributes to creating conditions for the approval of the basic principles.”
