This is the recorded conversation of the first meeting held between President Nixon and President Echeverría. Also in the room are Alexander Haig and translator Donald F. Barnes. After a long discussion of the salinity problems of the Colorado River water flowing into Mexico, Echeverría and Nixon spend most of their time together discussing the spread of communism in the hemisphere. The Mexican President insists that the only way to combat the subversive activities of Fidel Castro and the attraction of Chilean President Salvador Allende is with increased private investment from the United States into Latin America. Nixon counters that the only way to promote increased investments is through "stability," and cautions Echeverría that American business fears the growing trend toward nationalist economic policies in the region and the accompanying threat of expropriation.
