These bilateral discussions between Barrow and Burnham were later expanded to include V. C. Bird of Antigua and the three leaders ultimately signed the initial CARIFTA Agreement (the Agreement of Dickenson Bay in Antigua) on December 15, 1965. The original date envisioned for the Caribbean Free Trade Area to come into existence, according to the Dickenson Bay Agreement, was May 15, 1967. However, as a result of shuttle diplomacy engaged by Dr. Eric Williams, Prime Minister of Trinidad and Tobago, (through one of his ministers, Kamaluddin Mohammed) this was postponed as in order to allow Trinidad and Tobago to be included in the agreement and to generally make the agreement region-wide from the beginning. Dr. Williams had for years been advocating the establishment of a Caribbean Economic Community and was now fearful that Barbados, Antigua and Guyana were planning to form a free trade area between themselves to the exclusion of Trinidad and Tobago. The push to make the free trade area a region-initiative was successful and the issue was discussed at the fourth Conference of the Heads of Government of Commonwealth Caribbean Countries in Bridgetown, Barbados in October 1967. There it was resolved to introduce the free trade area by May 1, 1968 with the delegations of Montserrat and British Honduras (Belize) entering reservations to the conclusions of the resolution due to the constitutional status of their governments at the time. As a result of this a supplementary agreement to the original Carifta Agreement was signed in Georgetown, Guyana on March 15, 1968, and in St John’s, Antigua on March 18, 1968, with Carifta Day set for May 1, 1968.
