Deputy Director General of IAEA for Safeguards Herman Nackaerts said after the 9th round of talks, held in Tehran last February, that the issue of modality was top on the discussions but the negotiators failed to agree on the final document.
He stressed that the IAEA considers itself duty-bound to continue dialogues with Tehran.
Iran and the IAEA have been in talks for one year on modality, which wants to clarify how Tehran would respond to the IAEA questions on PMD. Iran takes the 2007 modality as a good base for new modality.
It would be the 10th round of negotiations between the two sides since early 2012.
The US, Zionist regime and some of their allies have repeatedly accused Iran of pursuing non-civilian objectives in its nuclear energy program, an allegation Iran strongly rejects.
Tehran maintains that as a committed signatory to the Non-Proliferation Treaty (NPT) and a member of the IAEA, it is entitled to develop nuclear technology for peaceful purposes.
The IAEA inspectors have conducted numerous inspections of Iran’s nuclear facilities but have never found any evidence showing diversion from peaceful purposes in the Iranian nuclear energy program.
