As the economic role ofmultinational, global corporations expands, the international economicenvironment will be shaped increasingly not by governments or internationalinstitutions, but by the interaction between governments and globalcorporations, especially in the United States, Europe, and Japan. A significantfactor in this shifting world economy is the trend toward regional trading blocsof nations, which has a potentially large effect on the evolution of the worldtrading system. Two examples of this trend are the United States-Canada FreeTrade Agreement (FTA) and Europe 1992, the move by the European Community (EC)to dismantle impediments to the free flow of goods, services, capital, andlabor among member states by the end of 1992. However, although numerouspolitical and economic factors were operative in launching the move tointegrate the EC’s markets, concern about protectionism within the EC does notappear to have been a major consideration. This is in sharp contrast to theFTA; the overwhelming reason for that bilateral initiative was fear of increasingUnited States protectionism. Nonetheless, although markedly different in originand nature, both regional developments are highly significant in that they willfoster integration in the two largest and richest markets of the world, as wellas provoke questions about the future direction of the world trading system.
