In response to Iran's unwillingness to give up its nuclear ambitions, the UN Security Council adopted Resolution 1737 last December, which provided for sanctions against Iran banning activities involving uranium enrichment, chemical reprocessing, heavy water-based projects, and the production of nuclear weapons delivery systems.
Gholamreza Agazade, Iran's vice president and head of the Atomic Energy Organization of Iran, said the UN Security Council resolution had brought about new legal complexities, and even before its adoption Iran said it would not comply with it.
Iran has been at the center of international concerns since January 2006 over its nuclear program, which some countries, particularly the United States, suspect is geared toward nuclear weapons development. Tehran has consistently denied the claims, and says it needs nuclear power for civilian purposes.
At the same time, Agazade said Iran is continuing its cooperation with the International Atomic Energy Agency.
