The Caribbean Committee was an allianced formed in i39 by the Dominican Republic, Cuba, and Haiti. Negotiations between group officers led to the division of caribbean lands, agreements on allowable future expansion, and a defensive pact between committee members through a secret document called The Caribbean Mutual Welfare Treaty. Later member additions were never made but the dissolution of the Canadian state and subsequent exodus to their independent island state of Jamaica resulted in the expansion of the member list anyways when that island afterwards joined the nation of Cuba. A copy of the plain text of that document is included below:

A Treaty for the Mutual Welfare of the Caribbean States

In order to preserve the prosperity and peaceful cooperation of these separate and free states, special diplomatic relations are desired to be arranged. The independent member states of República Dominicana, Gobernación de Cuba , and Imperio de Haiti hereby declare these articles of alliance.

Article One

The States so represented and agreed herein shall not form declarations that would create a state of war between themselves and another member state of the treaty, and that violent action undertaken by one nation upon another also be considered actions taken upon the remaining undeclared treaty members, unless it is understood prior that temporary hostilities were to be desired by those states. 

Article Two

In such an event as a delcaration of war having been received and understood as a state of war being formed against a signed treaty member, other members of the treaty shall endevour to defend against those defending and rise to their aid. Those signed shall not be compelled to render aid in such a circumstance as a fellow treaty member having first entered into hostilities with a foreign entity and so issued their declaration first.

Article Three

Member states shall not act to remove, detain, or execute citizens of another fellow member state from the borders of their lands except where need dictates or if violent offense has preceeded.

Article Four

The presence of an enemy which presents itself as a threat to the safety and freedom of the majority of member states, and if a declaration of war is expected to be forthcoming from such an entity, there shall be action taken by which a larger national entity is formed that is comprised of all member states. In such an instance, members will disband their national entities and form a larger coalition of confederate states under a governing body of war comprised of all member states, until such time as that threat to sovereignity has been eliminated.

Article Five

An alliance between a member state and another state which is itself comprised of criggers is to be considered a violation of the treaty and that all article are annulled between that state who has violated the treaty and all other member states. Diplomatic ties of other varieties which are to be held as violations are here listed: mercenary contracts, defensive pacts, exclusive trade agreements, and free trade. Where it is understood that violations of these kinds apply only to diplomatic action with a crigger state.

Consequences As a result of the treaty, Caribbean states acted in most instances as a single unit and political and war action was made with cooperation of every member state in attendance. The large and defining wars on the continents between The United States and Columbia [hyperlink this] throughout both weeks of play did not touch the Caribbean states even though they participated in them. War was limited to the comparatively minor conflict of the Cuban-Dominican Brother War [hyperlink this] and represented the only instance of Caribbean land changing hands.
