This paper uses the political reports of the CCP national congress as raw data and applies qualitative comparative analysis to investigate the conditions and the relative importance of domestic and international factors influencing China's policy toward the United States. The results of this analysis suggest that the conditions for China's cooperation and conflict toward the U.S. are different. China's revisionist preference is the necessary condition for its conflictive policy toward the U.S. However, when analyzing the conditions of China's cooperative policy toward the U.S., a combination of American lead in the U.S.-China power parity and the U.S. cooperative policy toward China is the necessary condition to ensure China's cooperation toward the U.S. In other words, without a revisionist proclivity, it is unlikely that China would choose to enter into conflict with the U.S., and China's cooperation toward the U.S. is a reaction to Washington's cooperation toward China and a reflection of the power disparity between the two countries.
