Sheibani said the goal of his country was peaceful, "we see no reason why we should stop peaceful activity."
He said all of Iran's nuclear facilities had been allowed to be under control and had been inspected for 14 times since March 2008.
Sheibani said "we need no nuclear military equipment", pointing out that Iran is "a religious, Islamic country. The Koran says, the one who kills an innocent people, kills a whole nation. Therefore, we have no mass destruction weapons."
In response to the questions on the missile tests last week, Sheibani said those missiles were "purely defensive weapons" and "it is a defending method."
Western countries, headed by the United States doubted that Iran's nuclear program was for military use, they have pushed the UN Security Council to impose three sanctions against Iran since December 2006, in order to compel Iran to stop its uranium enrichment activity. IAEA also sent many times inspectors to Iran to exam its nuclear facilities.
According to the latest schedule, Iran's chief nuclear negotiator Saeed Jalili would talk with world powers in Geneva on Saturday about its disputed nuclear program.
