Trade Diplomacy Transformed: Why Trade Matters for Global Prosperity reveals how three major transformations over the past two centuries in how and why trade diplomacy is done have shaped the essential movement of goods, services, capital and labour across borders, as buyers and sellers meet in the global marketplace. Beginning with the intimately linked origins of diplomacy and international trade in ancient history, the narrative explores the tariff negotiations that first liberalized international trade in the nineteenth century, the emergence and growth of institutions like the European Union and the World Trade Organization, and the recent rapid explosion in the diplomacy of trade dispute resolution. In its provocative conclusion, Trade Diplomacy Transformed argues that, if it is to remain effective as a venue for the globe's trade diplomacy, the WTO must reform itself to become more like the EU.
