Aqazadeh is likely to talk about the technical aspects of the Iranian program and is likely to address the issue of "alleged studies of weaponization" attributed to Tehran by Western countries, the report said.

He will also discuss Iranian nuclear activities with IAEA chief Mohamed El-Baradei in Vienna.

The Vienna-based UN nuclear watchdog said recently in a report that Iran has shown a lack of cooperative sincerity with the international community in solving its nuclear issues, calling on the country to cooperate in this regard.

According to the report, Tehran said the IAEA had been unable to make much progress in investigating Iran's controversial nuclear program.

However, the IAEA also pointed out that Iran has still a long way to go to develop the atom bombs.

Representatives from the United States, China, Russia, Britain, France and Germany on Friday agreed to submit to UN Security Council a draft resolution reaffirming existing sanctions on Iran.

The United States and its allies have accused Iran of developing nuclear weapons, but Iran insists that its nuclear program is only for peaceful purposes.

Iranian President Mahmoud Ahmadinejad shrugged off international sanctions threat on Thursday. "Whatever they do, Iran will continue its activities. Sanctions are not important," he told a news conference. "The era of such threats has ended."

Iran till now has been under three UN sanctions over its disputed nuclear program.
