The advisor to the Leader of the Islamic Revolution on international affairs said the nature of negotiations does not include imposing one's opinion on the other side, rather it involves meeting the other party halfway, with a view to accommodating differing interests of both sides.
Ali Akbar Velayati made the remarks in reference to the recently concluded accord between Iran and world powers over Tehran's nuclear program, Fars news agency reported on Tuesday.
He said the text of the Joint Comprehensive Plan of Action -- the official name of the nuclear deal -- is "not flawless" and has some weaknesses.
"The negotiators themselves do not believe the text on which they reached agreement is ideal and perfect," but the negotiating team has undoubtedly made every effort to safeguard national interests, he said.
The senior official ruled out talks with the US on any issue other than the nuclear dispute, stressing that the Leader has authorized no government official to negotiate with the US on bilateral ties or regional challenges, as "the West has proved it is not trustworthy in this regard."
Velayati also reiterated that no one is allowed to interfere in Iran's defense and military affairs or inspect its military sites.
