This document discusses patterns of international trade and trade groupings. It identifies key topics like changes in trade flows between developed and developing countries and the potential impact of emerging economies like China and India. It also examines the volume of world trade exports and GDP from 1950 to 2008, differences between export and GDP growth, and the composition of different geographical regions and trade groupings like ASEAN, NAFTA, EU, and WTO.
