The interregional economic complementarities under consideration are part of a long-standing trend. Trade liberalization and the increasing internationalization of capital have led to a growing interdependence between different economies. Consequently, the correlation between trade liberalization and economic development is leading to regional specialization and complementarity while shaping a new economic geography. Furthermore, the strengthening of inter-African economic and trade cooperation, particularly through bilateral or multilateral trade agreements, is an effective tool for promoting inter-African economic exchanges and attracting foreign investment. The gradual opening up of the Moroccan economy to the outside world is improving its integration into the global economy. Nevertheless, the new demands of traditional foreign markets require the national production system to diversify its economic partners while exploiting other South-South complementarities.
