Argentine-Brazilian contradictions as a factor of disintegration in South America

At the beginning of the 21st century, international relations in South America are developing in a paradigm of regionalization, manifested in emergence of multiple social associations on the continent, linked to each other not only geographically but also functionally. In parallel, trends of fragmentation and polarization, resulting from the crisis of Latin American multilateralism and from political heterogeneity established by the results of the next electoral period, are directly or indirectly influencing the nature of regional relations. In this context, and given their impact on regional affairs, the analysis of the current state of relations between Argentina and Brazil, characterized by polarized positions on a range of issues, deserves particular attention. The author chose a systemic approach to the analysis of international relations and the current foreign policy situation as the main methodological tool to achieve the goal of research. This, in turn, allowed the author of this article to consider South America as a regional subsystem, within which political systems and regimes compete, including for the choice of the vector of sub-regional development. The article demonstrates that recently the Argentine-Brazilian contradictions have fueled and strengthened political and ideological heterogeneity of the whole South American continent. In addition, the author cites different visions of formats and vectors of integration development of associations and subregional organizations in South America. According to the author, the actions of the governments of Alberto Fernández and Jair Bolsonaro make it quite difficult to implement and put in practice the necessary measures and formulated strategic goals, as well as to determine the vector of future development for Latin American states.
