The statement comes after Iran's Foreign Minister Abbas Araghchi said in an interview that there is a debate about whether the country should change its nuclear doctrine. He points out to the British newspaper The Guardian that it is still just a discussion.
We currently have no intention of exceeding 60 percent enrichment, he says.
The international community has long feared that the arch-conservative Islamic republic is trying to develop nuclear weapons. Iran has claimed that its nuclear energy program is for civilian use and insists that it has the right to enrich uranium for nuclear energy.
But in the country, frustration is growing over the sanctions that Tehran believes should be lifted. A week ago, the International Atomic Energy Agency (IAEA) adopted punitive measures against Iran for "lack of cooperation". This led Iran to respond by announcing that "new and advanced" centrifuges that can better enrich uranium will be put into operation.
On Friday, Iran is to hold nuclear talks with France, Germany, and the UK in Tehran.
