The Stockholm International Peace Research Institute published in December 2011 a report titled Arms Flows to Sub-Saharan Africa by Pieter D. Wezeman, Siemon T. Wezeman and Lucie Beraud-Sudreau.
While there is little transparency in arms transfer information, SIPRI states that China, Russia and Ukraine have consistently been among the largest suppliers of major arms to Sub-Saharan Africa (SSA) since 1996. The United States has provided 2-3 percent of major arms to SSA since 1996.
During 1996-2000, Ethiopia, Eritrea, Sudan, Uganda, and Kenya were among the ten largest importers of major arms in SSA.
During 2001-2005, Sudan, Ethiopia, Eritrea, and Uganda were on the list of ten highest importers.
During 2006-2010, only Sudan and Kenya in the Horn of Africa were on the list of ten highest importers.
