"Iran seeks nothing beyond its rights based on the Non-Proliferation Treaty," he was quoted by the official Islamic Republic News Agency as saying. "All nuclear activities [in Iran] have been peaceful and will remain so."
Rouhani made his comments in Tehran during a meeting with former U.N. Secretary-General Kofi Annan, who arrived in Iran as part of a delegation from The Elders, a peace advocacy group led by former world leaders.
Annan said Monday nuclear agreements with Iran "need to be sustained to achieve final agreement."
Iran received sanctions relief earlier this month for implementing the terms of a multilateral nuclear deal reached last year in Geneva, Switzerland. Iran said it would curb its nuclear research activity for the duration of the six-month agreement.
IRNA reported a three-man team from the International Atomic Energy Agency arrived Tuesday in Iran to visit the Gachin uranium mine near the port city of Bandar Abbas.
The visit was in line with agreements made in November between the Iranian government and the IAEA. IRNA reports the inspectors return Wednesday to Vienna to review their findings.
