Official Yerevan should maximum keep away from US ambassador figure, said Stepan Grigoryan, the head of Analytical Center on Globalization and Regional Cooperation told to the PanARMENIAN.Net reporter. "America is a great country and in any case will nominate the candidate it needs right now. The ambassador will protect US interests; currently America needs just this. I think we should not dispose the future ambassador to us from the very beginning." Grigoryan said. He also stressed that the Armenian Diaspora, which is against Richard Hoagland's nomination, does its work. "They are US citizens and can do whatever they consider necessary. Armenians should not interfere." Grigoryan thinks.
