stop the spread of malaria, and rebuild broken nations from their genocidal pasts. One of the most notable programs initiated by Bush is the PEPFAR (President's Emergency Plan for AIDS Relief) Program, which was a commitment of $15 billion over five years (2003–2008) from the United States to fight the global HIV/AIDS pandemic. As of September 2007, the program estimated that it had supported the provision of antiretroviral treatment to approximately 1,445,500 people, mostly in Africa. Alternate Delegate to the United Nations Kelly Craft advised the US Ambassador to the UN on US engagement in Africa. Craft also gave a speech to the UN General Assembly on the investment the U.S. and other nations were making to fight HIV/AIDS in Africa and malaria in Africa, and promote development there.

Furthermore, to the signing of the law, Bush signed another executive order that confirms the existing sanctions but eases some on parts of southern Sudan. It also includes exceptions to facilitate the flow of humanitarian aid to Darfur. On the other side the order toughens some sanctions, including a provision that bars any American from engaging in oil-related transactions in Sudan. The order comes as the Bush administration's new special envoy for Sudan, Andrew Natsios, began a trip to Sudan, where he plans to meet with government officials and visit war-torn Darfur. In response to the Government of Sudan's continued complicity in unabated violence occurring in Darfur, Bush
