“…With a total membership of 15 countries (Angola, Botswana, the Democratic Republic of the Congo, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe), the SADC as a whole constitutes about 37% of Africa's total gross domestic product (GDP) during 2003 to 2012 (UNCTAD, 2015). It is an organisation that strives for regional integration to promote economic growth, security and peace in southern Africa (Abdulrahman et al, 2015;Anyanwu and Yameogo, 2015;Pelinescu, 2015). Since its inception, the SADC has formulated policies and strategies for regional integration in support of sustained economic growth and development in the region with the expected economic benefits of increased market size, improved intra-regional trade, and investment flows (World Bank, 2015;WEF, 2014).…”
