Iran's Ambassador to the IAEA Ali Asghar Soltanieh and the agency’s Deputy Director General and Head of the Safeguards Department Herman Nackaerts opened the talks on Wednesday.
The ongoing talks are the 10th round of the negotiations between Iran and the IAEA over the Islamic Republic’s nuclear energy program since early 2012.
Soltanieh on Monday said that he expected progress to be made in this round of the talks.
The previous round of the negotiations was held in mid-February in Iran’s capital, Tehran.
