The problem of linkage between “nontrade” subjects and the World Trade Organization is certainly one of the most pressing and challenging policy puzzles for international economic relations and institutions today. It is extensively and harshly debated by political leaders and diplomats, at both the national and the international levels of discourse, and is one of several issues that derailed the WTO Third Ministerial Conference in Seattle in late 1999. It also posed problems for the Fourth Ministerial Conference in Doha, Qatar, in November of 2001, and it threatens to derail the successful functions of the WTO itself.
