This report aims to present how the techniques of conflict negotiation and rational decision making are absent in the Venezuela Brazil crisis. The nonadoption of good business practices by political and diplomatic agents aggravates the day-to-day of the peoples involved in the litigation. The option for modern negotiating instruments and the presence of an endogenous mediator is the proposal, as it would greatly facilitate the development of regional governance. To support the research, the report focuses on classical and contemporary literature, which covers topics such as: conflict transformation, black negotiation, newgotiation, process alternative, Theory Problem Solving, the Nobel economics of 2017 among other striking reflections.
