After the terrorist attacks on September 11, 2001, the United States faced a challenge in enlisting the full support of the People’s Republic of China (PRC) in counter-terrorism. This effort raised short-term policy issues about how to elicit cooperation and how to address China’s concerns about military action (Operation Enduring Freedom). Longer-term questions have concerned whether counterterrorism has strategically transformed bilateral relations and whether China’s support has been valuable and not obtained at the expense of other U.S. interests.
