The aim of this essay is to examine how the foreign relationships of Ethiopia has developed as a result of the construction and filling of the Grand Ethiopian Renaissance Dam between 2011 and 2021. This essay therefore asks: How has Ethiopia’s foreign relations with the EU, Egypt, Sudan and China changed, have those relationships become more conflictual or cooperative, and how could potential changes be explained using a constructivist perspective? Constructivism is used as a means of explaining changes in the statements, positions and policies of these countries through concepts such as “norms” and “identities”. It additionally utilizes concepts from other studies such as “Hydro-hegemony”, “Benefit Sharing” and “Ethiopian renaissance”. It uses the BAR-scale from Wolf et al. (2003) to determine the different stages of Ethiopia’s relationships. The study concludes that Ethiopia’s relationship with the EU and China have progressed positively as a result of the GERD, and they have now started considering Ethiopia a more equitable partner for further cooperation. The relationship with Egypt and Sudan initially improved, with new Ethiopian norms of cooperation and equitable utilization becoming mainstay. However, Ethiopia’s unilateral action during recent events broke these norms, and has turned the relations conflictual once again.
