General Treaty
In 1991 the integration agenda advanced with the creation of the SICA, which provided a legal framework to resolve disputes between member states. SICA includes seven Central America nations and the Dominican Republic, which is part of the Caribbean. Central America has several supranational institutions, such as the Central American Parliament, the Central American Bank for Economic Integration and the Central American Common Market. The Central America trade bloc is governed by the General Treaty for Economical Integration (the Guatemala Protocol), which was signed on 29 October 1993. The CACM has removed duties on most products throughout the member countries, and has unified external tariffs and increased trade within its members. The bank has five non-regional members: Argentina, Colombia, Mexico, the Republic of China and Spain.
