This work studies the development of bilateral relations in two pairs of states (dyads): Argentina-Brazil and Argentina-Chile. It takes on a moderate constructivist approach that incorporates into the analysis of international relations the role of identities, ideas and perceptions as well as of material forces, and understands that the former are affected and changed during interaction. It also uses to securitization theory to explain how issues come or cease to be considered security matters through social constructions.
