The relevance of the International economic institutions and Economic Development Agreements (EDAs) in the world today cannot be overemphasized. Several scholars have opined that they engender developments, particularly, in the country or countries of interest, and/or where the EDAs have binding force. In the same vein, the concept and principles of sustainable development balances the need for economic advancement with the need to preserve global environment to the benefit of the present and future generation. This paper examined the role of international economic institutions and economic development agreements in pursuing sustainable development. From the examination, it was observed that EDAs executed between countries now consider environmental factors and other aspects of sustainable development as veritable elements. And that Sustainable development has reshaped the interpretation of key provisions within the WTO’s agreements.
