The adoption of United Nations Security Council Resolution (UNSCR) 1929 on June 9, 2010 expanded significantly the breadth and depth of international sanctions in place against the Islamic Republic of Iran, establishing a strong, targeted, and comprehensive multilateral sanctions regime. It demonstrated the determination not only of the United States, but of the international community, to hold Iran to its international obligations regarding its nuclear program, and to prevent it from developing nuclear weapons. We are working with the international community to vigorously implement UNSCR 1929.
