ABC countries, or ABC Powers, is a term sometimes used to describe the South American countries of Argentina, Brazil and Chile, which are seen as three of the most powerful and wealthy countries in South America. They have worked together to develop common interests and a coordinated approach to issues in the region.
On May 15, 1915, the ABC Powers met again to sign a more formal treaty, designed to develop cooperation, nonaggression and the arbitration of disputes. It was formulated to resist United States' influence in the region and to establish a mechanisms for consultation among the three signatory countries, such as setting up a permanent mediation commission. The official name was the Consultation, Non-Aggression and Arbitration Pact.
Although the treaty was not official until it was ratified by Brazil, much of the foreign policy of the three signatories between 1915 to 1930 followed the basis of consultations and mutual initiative which the ABC Pact envisaged. To this end, the press used the name "ABC Pact" when the signatory countries co-operated to pursue integration initiatives in South America, concluded official agreements or actions regarding foreign policy, or promoted ideologically and politically similar organizations within the region.
