a declaration adopted on Mar. 6, 1945, as the principal statement of the Inter-American Conference on Problems of War and Peace, which was held at Chapultepec Castle, Mexico City.
The preamble to the Chapultepec declaration discusses mutual aid and inter-American solidarity. The first part of the declaration, which deals with questions of legal equality and independence, asserts that any encroachment on the integrity, territorial sovereignty, or political independence of any American nation will be regarded as an act of aggression against all the nations and will be answered by collective action, subsequent to consultation among all the nations.
The second part of the declaration contains recommendations on a procedure for applying sanctions in response to threats and acts of aggression. The third part proclaims that the principles underlying a regional consensus pertaining to the peace and security of the western hemisphere shall reflect the goals and principles of the future international organization (the UN).
The USA used the Chapultepec declaration to establish under its domination a military and political bloc of American nations.
