Currently,a debate about the country's China policy is underway in the United States,which is the biggest and the most significant debate since 1989.The debate is mainly between the United States'China experts,scholars of international politics and foreign affairs experts,and includes many former government officials.The massive number of reports,dissertations and journals on the topic of whether the China policy of each US government has been a failure since Richard Nixon's visit to China in 1972 has been described as a "tsunami" by some scholars.Two of the main questions being debated are:Is the state of both cooperation and competition in Sino-US relations sustainable? Should the next president adjust or even change the United States' policy toward China?1 The views expressed in the debate can be roughly divided into those of hard-liners,those of accommodators and those who advocate maintaining the current policy.
