Book excerpt: A small group of developing countries are transforming the global economic landscape. Led by China, India, and Brazil, these rising economic powers pose varied challenges and opportunities for U.S. economic interests and leadership of the global economy. They also raise significant policy issues for Congress, including the future direction of U.S. trade policy and negotiations, as well as for the multilateral economic institutions that have historically served as the foundation of an open and rules-based global economy. This book examines the ongoing shifts in global trade and finance and projected future trends resulting from the emergence of these economies.
