China's rise as a leading economic and military power is among the most epic developments in the twenty-first century. In terms of the theoretical implications of China's rise, the most prevailing theory is A F K Organski's power transition theory, whose logic has been explicitly or implicitly applied by various scholars and analysts to analyze Sino-American relations.

As the Chinese Ambassador to the United States pointed out, the strategic significance and global impact of Sino-American relations have been increasing.
