The objective of the study is to investigate the asymmetric impact of the World Trade Organization (WTO) across developing countries. We also demonstrate the lack of homogeneity between these countries in terms of their market growth and their dependence on natural resources.

We found that emerging resource-rich countries most

Finally, accession to WTO does not increase trade in natural resources for any specific category of countries discussed in this study.
