This report provides background information and issues for Congress on China's naval modernization effort and its implications for U.S. Navy capabilities. The question of how the United States should respond to China's military modernization effort, including its naval modernization effort, is a key issue in U.S. defense planning and budgeting. Many U.S. military programs for countering improving Chinese military forces (particularly its naval forces) fall within the U.S. Navy's budget.

U.S.-China economic ties have expanded substantially over the past several years. China is now the third largest U.S. trading partner, its second largest source of imports, and its fourth largest export market. However, U.S.-China commercial ties have been strained by a number of issues, including a surging U.S. trade deficit with China, China's refusal to float its currency, and failure to fully comply with its World Trade Organization (WTO) commitments, especially its failure to provide protection for U.S. intellectual property rights (IPR). This report explores these issues in detail, especially concerning the lack of protection for U.S. IPR.
