Regional integration refers to nation states coming together to cooperate functionally, economically, and politically for mutual benefit. Examples include the Organization of Eastern Caribbean States and the African Economic Community. Regional integration aims to overcome challenges facing regions like unequal resource distribution and aid development. Challenges include geography, unequal resources, and different growth stages, but opportunities include common history, culture, and issues. Stages have included the West Indies Federation in the 1960s and the Caribbean Free Trade Association formed in 1965 to unite economies and represent the Caribbean internationally. The Caribbean Community formed in 1973 to further economic integration, coordinate foreign policy, and enable functional cooperation across areas like health, education, and the environment.
