Abolfazl Zohrehvand, a member of the Iranian parliament's national security and foreign policy committee, said the 2003 agreement, which led to the Tehran Declaration, was a "strategic mistake" that should not be repeated.
In October 2003, Iran agreed to suspend uranium enrichment and permit enhanced inspections by the International Atomic Energy Agency (IAEA) to demonstrate the peaceful nature of its nuclear program and avoid referral to the United Nations Security Council.
The agreement was signed by Iran's then-Secretary of the Supreme National Security Council, Hassan Rouhani, along with the foreign ministers of the United Kingdom, France, and Germany at Tehran's Saadabad Palace. It temporarily averted escalation of the nuclear dispute.
However, following the election of President Mahmoud Ahmadinejad in 2005, Iran resumed uranium conversion activities at the Isfahan facility in August 2005 and enrichment at the Natanz facility in early 2006. By April 2006, Iran announced it had successfully enriched uranium to a purity level of approximately 3.5%, marking a significant advancement in its nuclear capabilities.
Zohrehvand said in an interview with Didban Iran that Tehran agreed in 2003 to suspend enrichment, signed the Saadabad agreement, and fulfilled its commitments by sealing the Natanz enrichment facility and the yellowcake production facility in Isfahan.
