Tehran would not give up its right to develop its nuclear industry for peaceful purposes, and all parties involved in talks to revive the 2015 nuclear accord should respect this.
This is according to a statement issued by Iranian President Ebrahim Raisi on Saturday.
Eleven months of indirect talks between Iran and the United States in Vienna have stalled as both sides say Tehran and Washington require political decisions to settle the remaining issues.
"For more than the one-hundredth time, our message from Tehran to Vienna is that we will not back off from the Iranian people's nuclear rights... not even an iota," state media quoted Raisi as saying in a speech marking Iran's Nuclear Technology Day.
Raisi reiterated Iran's stand that its nuclear programme is solely for peaceful purposes.
The United States is considering removing Iran's Islamic Revolutionary Guard Corps (IRGC) from its foreign terrorist organizations (FTO) blacklist in return for Iranian assurances about reining in the elite force, Iranian and Western sources had told Reuters.
One Iranian diplomat told Reuters that Tehran had rejected a U.S. proposal to overcome the sticking point by keeping the IRGC's overseas arm, the Quds Force, under FTO sanctions while delisting the IRGC as an entity.
The IRGC is a powerful faction in Iran that controls a business empire as well as elite armed and intelligence forces that Washington accuses of carrying out a global terrorist campaign.
