This article analyses recent productions of Latin American thinking on international affairs. The reviewed cases and examples are interrelated, for they are explanatory and interpretative abstractions of processes and practices in the international field, characterized by a description of formulations, concepts and methodological contributions. The common feature of these dimensions is the will of their formulators to explain their national and regional political realities from their own perspectives. Recent contributions offer potential for generalizations from national cases. They account for new realities that may impact on the international and regional system of international affairs.
