On September 3, Mehdi Sobhani, the Iranian Ambassador to Armenia, stated that neither the peace agreement nor the statement signed by Armenia and Azerbaijan in Washington mentioned transport routes referred to as a "corridor." Instead, they only addressed the opening of routes that would give Azerbaijan access to Nakhchivan and connect Armenia by rail to Jolfa in Iran.

Sobhani explained that Armenia and the United States had reached a verbal, rather than written, agreement to establish an Armenian-American joint venture in Armenia to identify the operator and investor for the project. He emphasized that the initiative would be implemented entirely within the framework of Armenia’s national sovereignty and jurisdiction, regulated by Armenian security agencies, passport control, and customs procedures. "According to the agreement, this will be a kind of operatorship, not ownership of the route," the ambassador stated.

He added that the text of the statement between Azerbaijan and Armenia, with further details to be determined by both sides, fully reflected the five principles emphasized by Iran: “respect for national sovereignty, respect for the integrity of borders, jurisdiction, reciprocity and inviolability of borders, and therefore there is no reason to be concerned about this.”
