Chief of Iran's Atomic Energy Organization Gholam-Reza Aqazadeh will address the International Atomic Energy Agency (IAEA) General Assembly on Monday about the country's nuclear activities, Iran's Press TV reported Saturday.

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.

The UN Security Council unanimously adopted a resolution on Saturday to reaffirm its previous resolutions on Iran and demand full compliance from the Islamic Republic.

The six major countries – the United States, Britain, China, France, Russia, Britain and Germany – agreed on the text of the resolution on Friday in New York on the sidelines of the UN General Assembly's annual debate.

Resolution 1835 reaffirmed its previous resolutions on Iran since July 2006 but contained no new sanctions.

It reaffirmed "its commitment ... to an early negotiated solution to the Iranian nuclear issue and welcomes the continuing efforts in this regard."

It called on Iran "to comply fully and without delay with its obligations" under the resolutions, and to meet the requirements of the International Atomic Energy Agency (IAEA) Board of Governors.

Since 2006, the Security Council has passed four resolutions on Iran, three of which slapped incremental sanctions over its noncompliance with the UN's call for it to stop nuclear enrichment.

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.
