It is often alleged that PTAs involving the EC and the US include a significant number of obligations in areas not currently covered by the WTO Agreement, such as investment protection, competition policy, labour standards and environmental protection. The primary purpose of this study is...

The larger trading nations have been the main users of the WTO Dispute Settlement system during its first four years of existence (1995-1998).
