ABSTRACT
This chapter presents some theoretical considerations on how the participation in an existing trade agreement should affect one state's attitude toward future trade partnerships. It offers a brief overview of North American Free trade Agreement's (NAFTA) institutional design and the dynamic it induces. The chapter applies two areas of post-NAFTA trade negotiations: the western-hemispheric and transatlantic ones. The chapter explores what NAFTA has to offer in term of voice opportunities in order to verify the level and form of the expected voice deficit to which Canada and Mexico are confronted. It shows how central voice concerns have been in the divergences of preferences toward trade strategies one can establish between Canada, Mexico and the US. As in the case of hemispheric trade negotiations, transatlantic relations have been an area of extra-regional trade policies where our three 'amigos' have manifested diverging preferences.
