I do not think that the reactions coming from Turkey, Armenia and even Armenian Diaspora produce negative impact Protocol signing, TURKSAM Director Sinan Ogan told a PanARMENIAN.Net reporter. "President Sargsyan is subject to visit Turkey after the protocol that will be arguably signed on 10-11 October. There is not any problem about the match and Protocol signing, however I do not expect that documents will be approved soon. Although they may receive Armenian parliament's approval, Turkish parliament will be looking forward to a progress over Nagorno-Karabakh issue," Turkish expert said.
