A first effort to establish a Central American Common Market, CACM
(Spanish: Mercado Com_n Centroamericano, MCCA) was attempted in 1960 under the auspeices of the Organiztion of Central American States
(OCAS). A restructuring was started in 1973. Members include Honduras, Guatemala, El Salvador, Nicaragua and Costa Rica. The common market will cover all products traded within the region by the end of 1992. A second step toward regional integration will be the establishment of a common external tariff. CACM is associated with the Central American Bank for Economic Integration; headquarters are in Guatemala City, Guatemala.
