The official said Tehran could seriously consider a combination of exporting part of its highly enriched uranium (HEU) stockpile, diluting the purity of its HEU and a regional consortium for enriching uranium, but in return, Iran’s right to “peaceful nuclear enrichment” must be recognised.

“The negotiations continue, and the possibility of reaching an interim agreement exists,” the official said.

Iran’s Foreign Minister Abbas Araghchi said on Friday that he expected to have a draft counterproposal ready within days following nuclear talks with the United States this week, while US President Donald Trump said he was considering limited military strikes.

The senior official said Tehran will not hand over control of its oil and mineral resources, but US companies can always participate as contractors in Iran’s oil and gas fields.
