This is a study of the problem of managing foreign policy in federal states during a period of intensifying international interdependence. A significant result of this increased interdependence has been that the regional governments in federal states have become more actively involved in international affairs than ever before. This in turn has made it necessary for national and regional governments to develop ways and means of communication and bargaining in the area of foreign affairs. The book examines this problem through a comparative study of American, Canadian, Australian and German experience, and at the same time looks at related developments that are taking place within the European Community.
