Regional Blocs [PDF ebook] 
Building Blocks or Stumbling Blocks?

A topical study of regional arrangements covering ASEAN, SAARC and APEC in Asia, NAFTA and MERCOSUR in the Americas, SADC, SACU and ECOWAS in Africa, and the European Union, EFTA and Eastern Europe. The book argues that foreign direct investment is complementary to trade and most regional arrangements can create trade and induce growth so long as they remain open and non-discriminatory. But they could also become stumbling blocks to globalization. The book demonstrates how US and EU trade policy will be crucial in shaping the world economy.
