"The United States maintains a range of economic sanctions on the Government of Sudan. The United States generally restricts foreign aid because Sudan has been found, by the Secretary of State, to be a supporter of acts of international terrorism, is operating under a military dictatorship, and has fallen into arrears in its debt repayment. The United States has also suspended bilateral preferential trade treatment, restricted commercial exports and imports, denied the export of defense articles and defense services, and refused to support requests from Sudan for funding or program support in the international financial institutions for reasons related to terrorism, regional stability, and human rights--including religious freedom, worker rights, and trafficking in persons. [...] This report describes U.N. actions and U.S. economic sanctions currently in place on Sudan, and the exceptions to those sanctions. It will be updated as events warrant."
