Latin American foreign policy has drawn the attention of scholars since the 1960s. Foreign policy–related literature began to surge in the 1980s and 1990s, with a focus on both economic and political development. As development in the region lagged behind that of its northern neighbors, Latin American had to rely on foreign aid, largely from the United States. In addition to foreign aid, two of the most prevalent topics discussed in the literature are trade/economic liberalization and regional economic integration (for example, Mercosur and NAFTA). During and after the Cold War, Latin America played a strategic foreign policy role as it became the object of a rivalry between the United States and the Soviet Union hoping to expand their power and/or contain that of the other. This role was also explored in a considerably larger body of research, along with the decision of Latin American nations to diversify their foreign relations in the post–Cold War era. Furthermore, scholars have analyzed different regions/countries that have become new and/or expanded targets of Latin American foreign policy, including the United States, Canada, Europe, Asia, and the Middle East. Despite the substantial amount of scholarship that has accumulated over the years, a unified theory of Latin American foreign policy remains elusive. Future research should therefore focus on the development of a theory that incorporates the multiple explanatory variables that influence foreign policy formulation and takes into account their relative importance and the effects on each other.
