The official, Abolfazl Zohrehvand, says this limited cooperation will apply to the building of 10 new uranium enrichment facilities.
Tehran on Sunday announced it intends to build the new sites. The statement followed a strong rebuke from the Vienna-based U.N. agency and spiked Western concerns over Iran's nuclear intentions.
Zohrehvand says Iran will only inform the International Atomic Energy Agency after it installs the new sites — not while their construction is in the planning stages, as demanded by the U.N. watchdog.
Zohrevand's comments were carried by the official IRNA news agency on Friday.
