IRNA - Head of the Atomic Energy Organization of Iran (AEOI) said on Monday that everything in the nuclear industry is on the right track.
Speaking in a local ceremony, he added: 'We know well how to reverse the nuclear option if the Joint Comprehensive Plan of Action (JCPOA) is violated.'
The other side of nuclear talks will be seriously harmed, Salehi added.
He said that the nuclear talks was an exemplary model of negotiations in the world and had public and international reflections.
Salehi said that the government used the opportunity of direct talks in best way to progress the negotiations forward.
If Iran had not inked the nuclear deal, the situation would have been much more difficult now, he said.
It is not fair to say we have not witnessed a positive change after the JCPOA, Salehi said in a reference to improvement of Iran's oil export, trade and transportation, etc over past two years.
'We are making advancements in the nuclear industry,' he underlined.
