Iran said it will accept monitoring of its nuclear program as called for in the global non-proliferation treaty, but not any inspections beyond that.
Iranian President Hassan Rouhani said Sunday that any inspection beyond the legal framework of the treaty "would be a precedent, against the interests of all developing countries."
Rouhani made his comments as he met in Tehran with the visiting head of the United Nations nuclear watchdog agency, Yukiya Amano.
Amano made a one-day stop in the Iranian capital ahead of the August 25 deadline for Iran to provide information about its nuclear development program to the International Atomic Energy Agency.
Amano called the talks useful and said he was pleased that Iran pledged its cooperation in resolving questions about its nuclear program.
The United States and its Western allies have long suspected that Iran is developing a nuclear weapon, but Tehran said its nuclear development program is only for civilian purposes.
Iran wants to end crippling sanctions against its economy that the West has imposed to try to force it to abandon any development of nuclear warheads.
