Saavedra Lamas drafted the Antiwar Pact of 1934, and it was signed by Italy, USA and 14 Latin-American countries. The Antiwar Pact of 1934 was intended as a means to secure an armistice in the Gran Chaco War between Bolivia and Paraguay. It condemned all forms of aggressive war, and any territorial change not effected by peaceful means was not to be recognized.
The International Mediation Committee concisted of representatives from Brazil, Chile, Peru, Uruguay and the United States.
A committee (Commissiòn Nacional de Homenaje al Ministro de Relaciones Exteriores, dr. Carlos Saavedra lamas) was established in order to promote Saavedra Lamas' candidacy.
