Two of the most significant regional organizations to emerge in Southern Africa in recent years are the Southern African Development Coordination Conference (SADCC), with nine members, and the Preferential Trade Area for Eastern and Southern Africa (PTA), comprised of fourteen states including five SADCC members. Although their purposes and programs are similar and steadily converging, SADCC and PTA exhibit distinct differences in their origins, memberships, institutional structures, financial patrons, ideologies, and strategies. Although national development remains the ultimate aim of both bodies, reducing external dependency, especially in the case of SADCC on South Africa, and regional cooperation are seen as essential to success. While obvious areas of conflict exist, the two organizations may be able to restrain their rivalry in the interests of their members and possibly of their own survival.
