"Regional co-operation and integration in Southern Africa owes its origin to historical, economic, political, social and cultural factors that have created strong bonds of solidarity and unity among the peoples of Southern Africa. These factors have contributed to the formation of a distinct Southern African personality and identity that underpins political and economic co-operation." This is according to the final version of SADC's Regional Indicative Strategic Development Plan (RISDP). The document is designed to provide a long-term plan for development in Southern Africa.
