The U.S. government imposed economic sanctions against Sudan in 1997, due to the Sudanese government's alleged sponsorship of international terrorism and poor human rights record. The sanctions prohibited trade between the United States and Sudan, as well as investment by U.S. businesses in Sudan. In February 2000, the U.S. government extended its sanctions to include Sudapet and GNPOC. These sanctions were lifted after the Sudanese revolution of 2018/19 and ensuing negotiations between the two governments at the end of 2020.
