The increasing rivalries between China and U.S. starting from economic issues, diffusing to political and military dimensions, reassure the rational solutions presumed by power transition theory. By examining the combined effects of international systemic structure, international context, the impact of Chinese democratization, Taiwan Issue, the changing share of national capability, Chinese nationalism, and domestic politics, the paper builds an empirical model to analyze how these factors shape the patterns of Sino-American Conflict over time. The model identifies a new pattern of conflict due to the increasing interdependence of economy and specifies that comprehensive engagement enhances rather than threats to U.S. leading power. Therefore the model predicts more cooperation than confrontation in Sino-U.S. relations in the near future. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]
