Abstract
For the liberalists, the WTO would be indispensable as an umpire or promoter for liberal economy. Even for the reformers of the regime, say, environmentalists, activists or progressives, it would be, in the least, a necessary evil in view of the trade governance. Behind this world forum, however, we are able to identify the national actors, perhaps the trade diplomats, which are fairly substantial or powerful in some aspect to wheel ahead the interdisciplinary complexities entangled with the trade issues. The trade laws and public policy, at either national or international scale, would perhaps be an epitome most practically as the analytical tool of understanding. In this context, the paper deals with the USTR, one of most influential national trade offices, in the traditional rubric of public policy discipline.
