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 the counterterrorism fight against Al Qaeda. This effort raised short-term policy issues about how to elicit cooperation and how to address PRC concerns about the U.S.-led war (Operation Enduring Freedom). Longer-term issues have concerned whether counterterrorism has strategically transformed bilateral ties and whether China's support was valuable and not obtained at the expense of other U.S. interests.
