Iran Sanctions: New Act Underscores Importance of Comprehensive Assessment of Sanctions' Effectiveness

This testimony discusses our work on the implementation of U.S. sanctions against Iran. It discusses the continuing challenges the United States faces in (1) deterring the illegal transshipment of U.S. goods to Iran, (2) restricting foreign investment in Iran's energy sector, and (3) assessing the overall effectiveness of U.S. sanctions. In addition, it discusses how the Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010 (signed into law on July 1, 2010) addresses these challenges. The United States has imposed multiple sanctions against Iran to deter it from developing its nuclear program, supporting terrorism, and abusing human rights. The United States has banned most U.S. trade and investment with Iran and prohibited firms from knowingly transshipping U.S. goods to Iran through other nations. The United States has also acted to limit Iran's ability to explore for, extract, refine, or transport its petroleum resources. The Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010 expands existing sanctions against Iran and requires the Administration to report on information related to the sanctions. This testimony is drawn from prior GAO work related to sanctions against Iran. We conducted this work in accordance with all sections of GAO's Quality Assurance Framework and generally accepting government auditing standards, as appropriate.
