The Gambia plays an active role in international affairs, especially West African and Islamic affairs, although its representation abroad is limited. As a member of the Economic Community of West African States (ECOWAS), The Gambia has played an active role in that organization's efforts to resolve the civil wars in Liberia and Sierra Leone and contributed troops to the community's ceasefire monitoring group (ECOMOG) in 1990 and (ECOMIL) in 2003. It also has sought to mediate disputes in nearby Guinea-Bissau and the neighboring Casamance region of Senegal.
