Extracted from CRS report

Via the CRS:

Under the FY2013 budget request, aid to Africa would decline by 10% from the current level to $6.4 billion; U.S. aid to the Near East would increase by 12% to $9.0 billion, largely due to support for the Arab Spring; and aid to South Central Asia would increase by 6% to $5.3 billion. Aid to Africa primarily supports HIV/AIDS and other health-related programs while 88% of the aid to South Central Asia is requested, largely for war-related costs, in Afghanistan and Pakistan. The Near East region continues to be dominated by assistance to Israel ($3.1 billion), Iraq ($2.0 billion), Egypt ($1.6 billion), and Jordan ($0.7 billion). The Western Hemisphere’s projected relative decline in FY2013 is attributable to a reduction in funding of ESF and INCLE for Colombia. Europe and Eurasia’s 14% decline is largely due to progress made by many countries in the region and other more pressing global priorities. Aid to East Asia and Pacific remains relatively low and consistent with past years’ levels.
