From the Summary: "Several laws restrict U.S. support for World Bank lending to Iran. Despite U.S. opposition, the World Bank has provided loans to Iran on several occasions over the past five years, and disbursements on these loans appears to be increasing. Several pieces of legislation: H.R. 1400, 'Iran Counter-Proliferation Act' and S. 970, 'Iran Counter-Proliferation Act of 2007' would cut future U.S. funding to the World Bank if the Bank makes new loans to Iran. This report will be updated as events warrant."
