Regional leaders created the Economic Community of West African States (ECOWAS) on May 28, 1975 in Lagos, Nigeria. ECOWAS is comprised of 15 countries, which include: Benin, Burkina Faso, Cape Verde, Cote dIvoire, The Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone, and Togo. The leaders established ECOWAS to promote regional integration and economic growth in West Africa, as Well as to create a monetary union in the region. However, ECOWAS has encountered problems in the process of regional integration including: political instability and lack of good governance that has plagued many member countries, the insufficient diversification of national economies, the absence of reliable infrastructure, and the multiplicity of organizations for regional integration with the same objectives.The Authority of Heads of State and Government is the governing body of ECOWAS. The Authority determines the general direction and development of the Community, as well as the realization of the Communitys objectives. The Authority elects an annual Chairman, with the 2006 Chairman being Nigers President, Mamadou Tandja. Under the Authority is the Council of Ministers, which is responsible for the proper functioning of the Community. In April 2002, the Council approved a procedure for the ECOWAS Trade Liberalization Scheme (TLS). The TLS entitles the manufacturers of approved products to customs duty exemption within ECOWAS member states. The procedure uses National Approval Committees, set up by member states, to handle the approval of products to be granted exemption under TLS. The 2002 decision by the Council abrogates a previous decision and grants the Council a monopoly for approving applications for such exemptions.In 1990, ECOWAS established the Economic Community Monitoring Group (ECOMOG), a multilateral military peacekeeping force to intervene in the civil war of Liberia. Since 1990, ECOMOG has been deployed in civil conflicts in Sierra Leone, Guinea-Bissau and CÔte dIvoire. The CÔte dIvoire disarmament and peace mission included ECOMOG troops from Benin, Ghana, Niger, Nigeria, Senegal and Togo. Overall, Nigeria has contributed the largest amount of troops, materials and financial support to ECOMOG missions. ECOWAS is seeking international support to enable it to train and equip the 15 battalions of troops pledged by member states. The training of the composite units facilitates their effectiveness in peacekeeping, humanitarian assistance and other missions for which they could be deployed.
