China finally entered the World Trade Organization (WTO) in 2001. The saga began in April 1999 when China shocked the world and the Chinese people by suddenly yielding to the demanding terms of the China-U.S. trade negotiations. China promised to open markets and drastically lower tariffs for a large number of products, even in sensitive economic sectors such as grain trades. Building on this bilateral agreement, the United States supported China in subsequent bilateral and multilateral trade negotiations with WTO member states. Since Deng Xiaoping's open-door policy in the early 1980s, this bilateral trade agreement has become a new landmark of China's long march to reintegrate itself into the global economy.
