The report discusses the question of how the United States should respond to China's military modernization effort, including its naval modernization effort, that has emerged as a key issue in U.S. defense planning. Admiral Michael Mullen, the Chairman of the Joints Chiefs of Staff, stated in June 2010 that "I have moved from being curious to being genuinely concerned" about China's military programs. The question of how the United States should respond to China's military modernization effort is of particular importance to the U.S. Navy, because many U.S. military programs for countering improved Chinese military forces would fall within the Navy's budget.

This report examines U.S. foreign assistance activities in the People's Republic of China (PRC), including U.S. Department of State and U.S. Agency for International Development (USAID) programming, foreign operations appropriations, policy history, and legislative background. International programs supported by U.S. departments and agencies other than the Department of State and USAID are not covered in this report.

This report considers potential implications for U.S.-China relations. China's actions for asserting and defending its maritime territorial and exclusive economic zone (EEZ) claims in the East China (ECS) and South China Sea (SCS), particularly since late 2013, have heightened concerns among observers that ongoing disputes over these waters and some of the islands within them could lead to a crisis or conflict between China and a neighboring country such as Japan, the Philippines, or Vietnam.
