Iran's senior nuclear negotiator, Abbas Araqchi, has said the International Atomic Energy Agency (IAEA) should close what they called the possible military dimensions (PMD) of Tehran's nuclear programme.
The PMD programme was in place in order to enforce Iran's nuclear agreement with world powers.
Araqchi's remarks came on the sidelines of a joint commission meeting in Vienna on Monday between Iran and the P5+1, -- Britain, China, France, Russia, the US, plus Germany, according to Press TV.
Both sides reviewed issues pertaining to the nuclear agreement implementation, he said, adding that representatives from both sides also discussed the need for the UN nuclear watchdog to end Iran's PMD case.
Discussions were conducted "in a positive atmosphere," he said.
Araqchi criticized a few issues in the latest IAEA report regarding nuclear explosive device development, when it came to Iran's previous nuclear activities.
His remarks alluded to last Wednesday's IAEA report where the UN nuclear agency found no credible evidence proving that Iran pursued nuclear bomb plans post 2009, nor delivery system research after 2011.
The IAEA and Tehran signed a roadmap which included Iran's past unresolved nuclear PMD issues, according to the historic Iranian nuclear deal.
Under the deal, Iran must scale back its nuclear programme, including its stockpile of low-enriched uranium - which it plans to do via a swap for non-enriched forms of uranium with Russia, to remove concerns it could be put to developing nuclear bombs, reported Reuters.
The report stated that Iran has implemented all necessary activities included in the roadmap, in cooperation with the IAEA.
The historic nuclear deal was signed on 14 July between Iran and the P5+1 group, where Tehran must significantly scale down its atomic plans in order to address Western countries' concerns over the alleged nuclear weapons programme.
The IAEA charged with the responsibility to monitor that process, and the IAEA board members states are expected to discuss the report and adopt a resolution by 15 December.
