From 1975 to 1989, Angola was aligned with the Soviet Union and Cuba. Since then, it has focused on improving relationships with Western countries, cultivating links with other Portuguese-speaking countries, and asserting its own national interests in Central Africa through military and diplomatic intervention. In 1993, it established formal diplomatic relations with the United States. It has entered the Southern African Development Community as a vehicle for improving ties with its largely anglophone neighbors to the south. In 1997, Zimbabwe and Namibia joined Angola in its military intervention in the Democratic Republic of the Congo, where Angolan troops fought in support of the Laurent and Joseph Kabila governments. It also has intervened in the Republic of the Congo (Brazzaville) in support of President Sassou-Nguesso.

Multilaterally, Angola has promoted the revival of the Community of Portuguese-Speaking Countries (CPLP) as a forum for cultural exchange and a means of expanding ties with Portugal and Brazil. During the peace process, the government fully cooperated with the UN Mission in Angola (UNMA), which concluded its mandate in mid-February 2003. Angola began a 2-year term on the Security Council in January 2003.
