"Iran can be flexible on the capacities and limits of enrichment, but cannot agree to stop enrichment under any circumstance because it's essential, and we need to rely on ourselves, not on empty promises," Majid Takht Ravanchi told Kyodo News in an interview on Saturday.
The Iranian officials have made clear that Iran would not compromise on its right to peaceful nuclear technology, including enrichment.
Iran views the American approach as closely aligned with Israeli Prime Minister Benjamin Netanyahu’s hardline demands for zero enrichment.
