China's December 2001 accession to the World Trade Organization (WTO) signified that the world's seventh largest economy and the United State's fourth largest trading partner would be subject to the multilateral organization's trade liberalizing requirements. China's accession agreement is a set of legal documents totaling more than 800 pages. In order to fulfill its WTO commitments, China will have to undertake numerous actions over the next 10 years, ranging from reducing or eliminating tariffs to improving the transparency of trade-related rules and regulations. GAO released its database of its analysis to assist Congress in analyzing, monitoring, and enforcing China's WTO commitments.
