European Union foreign policy chief, Javier Solana, handed Iran's Foreign Minister Manouchehr Mottaki a package of new incentives from the Iran six - China, France, Russia, the United States, Germany and Britain - on June 14. The proposals offer political, security and trade benefits to Iran.
"The study of the proposals is at the concluding stage. The Islamic Republic will express its position as soon as the review is over," Attar said.
Iran is currently under three sets of relatively mild UN Security Council sanctions for defying demands to halt uranium enrichment, which it says it needs purely for electricity generation despite Western accusations that the program is geared toward weapon production.
Iran maintains that it has never been involved in research into the development of nuclear weapons.
