In the late 19th and early 20th centuries, American foreign policy underwent a major shift toward expansionism and imperialism. This transformation was not only a natural result of the increase in American power, but also largely influenced by the mentality of national identity, American exceptionalism, cultural superiority, etc. The American images of China, influenced by this shift, had also undergone significant changes. China in the 19th century was seen as a byword for barbarism, but in the early 20th century, Americans began to talk about China’s awakening. A variety of changes in mentality and expansionist policies had turned the national imagination of Americans to imperialism, which was the driving force behind the change in China’s image. The change in China’s image had in turn affected U.S. policy toward China. However, on the other hand, the tradition of Orientalism had led American to regard China as a passive and static entity. China as a nation and Chinese laborers led the United States to view China as a “double other” rather than a free subject of thought or action. This ideology promoted the formation of the consensus of Open Door Policy and Chinese Exclusion.
