This work is the second in a series examining the changing nature of one of the United States most important relationships, the ANZUS Alliance, linking the U.S., Australia, and New Zealand. The volume describes the evolution of the three countries respective domestic economic structures, international economic orientations, and relationships with each other in the period since World War II. The study concludes that the most significant common economic interest of the three is the preservation and strengthening of an open international economic order and trading system, an interest sorely tested in the present difficult economic times. Still, the experts here find that Australia, New Zealand, and the U.S. must match trends toward greater economic interdependence with workable mechanisms and concerted action to achieve their truly common interests in the international economic system. This important work will be of interest to scholars in international relations, generally, and international economic systems, specifically.
