Some eighty delegates, most of them Latin Americans, gathered together at the Dorado Beach Hotel in San Juan, Puerto Rico, from March 1 to 4, 1960, to discuss the problems which surround relations between the United States and Latin America. The previous fall the Sixteenth American Assembly at Arden House had considered the same theme; its published proceedings were reviewed by John Plank in the H.A.H.R., Vol. XL (November, 1960), 613-614. The Spanish translation of the background reports by Herbert L. Matthews et al., which were also used at the San Juan gathering, are included in this present volume along with the speeches delivered by Governor Luis Muñoz Marín and Germán Arciniegas. In their final reports, both conferences agreed that social and economic reforms in Latin America were long overdue. But whereas the New York meetings underscored Latin America’s economic and strategic importance to the United States and the challenge of international communism, the Puerto Rican sessions urged more understanding on the part of the United States for the nationalistic aspirations of those countries. Moreover, they were more concerned with the nature of the means to be used in relations between the Americas.
