Economic and trade reforms begun in 1979 have helped transform China into one of the world's fastest-growing economies. China's economic growth and trade liberalisation, including comprehensive trade commitments made upon entering the World Trade Organization (WTO) in 2001, have led to a sharp expansion in U.S.-China commercial ties. Yet, bilateral trade relations have become increasingly strained in recent years over a number of issues, including a large and growing U.S. trade deficit with China, resistance by China to appreciate its currency to market levels, China's mixed record on implementing its WTO obligations, infringement of U.S. intellectual property (including through cyber espionage), and numerous Chinese industrial policies that appear to impose new restrictions on foreign firms or provide unfair advantages to domestic Chinese firms (such as subsidies). This book provides an overview of U.S.-China commercial relations, including major trade disputes.
