This book analyzes the interaction between international trade and investment on the one hand the environment on the other from a Least Developed Country (LDC) perspective. Accordingly, it investigates the experience of some African countries with a particular emphasis on Ethiopia. It explores the extent to which the WTO regime, as it is today, is environment-friendly. It examines the adequacy of the General Agreement on Tariffs and Trade (GATT) general exception under Art. XX (b and g) in enabling the WTO members comply with their rights and obligations under MEAs and other laws. It finds that the current WTO regime could have negative implications for Ethiopia's environmental concerns upon accession.
