Speaking to reporters in the city of Isfahan on Monday, Salehi said the Joint Comprehensive Plan of Action (JCPOA) could not undergo any changes during the process of scrutiny in Iran’s parliament.
With any change, the other side will blame the failure of JCPOA on Iran, and Tehran will consequently lose everything, he added.
Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) on July 14 reached a conclusion on a lasting nuclear agreement that would terminate all sanctions imposed on Tehran over its nuclear energy program after coming into force.
The 159-page deal has its own opponents and proponents both in Iran and the other countries that are parties to the JCPOA, particularly the US.
Diplomats have already made it clear that the document could be either approved or rejected, and no amendment or revision could take place.
Elsewhere in his comments, Salehi pointed to Iran’s cooperation with Russia in building nuclear power plants, saying the construction process of the country’s second nuclear power plant will kick off by March 2016.
Geological and seismological studies are now underway on the new nuclear power plant’s site, he noted.
On Saturday, head of Russia’s State Atomic Energy Corporation (Rosatom) said that preparation work for the construction of the second unit at Iran’s Bushehr nuclear power plant has begun.
In 2014, Iran and Russia agreed to build two new nuclear reactors on the Bushehr site, starting in the fall of 2015; Tasnim reported.
