The 1990s are likely to be known as the decade of the trading blocs, although these neo-blocs differ considerably from those of the 1930s. Countries are linking to liberalize the flow of trade and investments across their borders without necessarily raising external barriers. The European Community and the European Free Trade Association are linking to create a European Economic Area, and the United States and Canada have joined in negotiations with Mexico to conclude a North America Free Trade Agreement. In Asia, nations have been studying the idea of a similar arrangement for themselves.
