Within his visit to the US Azeri Foreign Minister (FM) E. Mammadyarov delivered a speech in the Carnegie Foundation. Speaking of the Nagorno Karabakh conflict, Mammadyarov noted that the Armenian and Azeri leaders and the two FMs hold meet periodically. ««The talks are held in a very hard situation, however I am cautiously optimistic over the coming meetings. I think there is light seen at the end of the tunnel, but we have to pass a long way to achieve it,» the Azeri FM said. «We will always be guided by the principle of territorial integrity in the talks,» he stated. Having noted that «different signals» from Yerevan reach Baku, E. Mammadyarov added, «Sometimes it seems we are moving forward, sometimes like we make no headway, as the development of the process depends on Armenia. They should understand that it is good time now for settlement of the conflict and they should seize the opportunity.»
