Minister of Foreign Affairs of the Islamic Republic of Iran said in an interview in answer to the question what group he deems more successful "Each group had their own characteristic features. But if you want me to give them marks I can not do that.”
Salehi continued "Each group has its own strong points. Mr. Rouhani was a really capable negotiator and he knew what to do. Prior to the talks he would hold lots of meetings with experts and used the consultations when he set for negotiations.”
"As far as I was present in his meetings I could see that he set time for them and was hard-working. He would stress that we must do our best so that the case is not referred to the Security Council. This was his strategy and he excelled at it,” he added.
