Abstract
In the past 30 years Argentina has lived with a Brazil, who has proposed itself as one careful and responsible big brother and, at the same time, carried a new role for South America. In turn, Argentina finds in the relationship with Brazil an international and also national political impact. However, coexists overtones of distrust regarding alleged Brazilian representation abroad. In this context, we stand at the interface of indicators and imaginaries in which perceptive statements are referenced. They end up always playing a central role in the assemble and decisions on political structures and, therefore, in this case, we chose to analyze how they influence the Argentine foreign policy related to the neighboring country. Also, we argue that perceptions are a fundamental variable for the formulation of foreign policy extents. In this article, we present three perceptions that currently coexist in Argentina with regard to Brazil.
