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 wealthiest countries in South America.
On May 15, 1915, the ABC Powers met again to sign a more formal treaty, designed to foment outer cooperation, nonaggression and the arbitration of disputes. It was formulated to resist American influence in the region and to establish a balance and mechanisms for consultation between 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 did not enter use until it was ratified by Brazil, a great degree 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 name "ABC Pact" is used by the press when the signatory countries co-operate to pursue integration initiatives in South America, conclude official agreements or actions regarding foreign policy, or promote ideologically and politically similar organizations within the region.
