The Caribbean Forum (CARIFORUM) is a subgroup of the African, Caribbean and Pacific Group of States and serves as a base for economic dialogue with the European Union. It was established in 1992. Its membership comprises the 15 Caribbean Community states, along with the Dominican Republic. In 2008, they signed an Economic Partnership Agreement with the European Union, though Guyana and Haiti had expressed reservations and did not attend the signing ceremony. Tensions within the group have grown over issues of trade and immigration; the Dominican Republic, with the group's largest economy, has expressed reservations over its current structure.
