The People’s Republic of China (PRC), in the eyes of its leadership, has been perceived as a unitary multiethnic state (duo minzu guojia), comprised of the Han majority and fifty-five ethnic minorities. State propaganda routinely emphasizes the inseparability of the Han from other ethnic groups that have seamlessly cohered into one harmonious whole in the course of five thousand years of history. The “ethnic minorities” (shaoshu minzu) concept attained its meaning during the minority identification project (minzu shibie) of the mid-1950s shortly after the establishment of the PRC. Yet, the ideas and principles of the Chinese national model formalized through the ethnic identification project are informed by the centuries of the Chinese central state’s expansion and absorption of new territories and people into its domain. The articulation of the Chinese territorial and cultural borders went hand in hand with the development of new forms of categorization and demarcation of difference encountered as Chinese borders expanded. Prior to the Republican period (1911–1949), to be Chinese was a matter of accepting and converting into Confucian norms. According to the rules of the governing order of imperial China, tianxia, practicing the Confucian ritual and ethical principles was sufficient to become Chinese (huaren). In the period of China’s forced opening-up to the outside world in the mid- to late 1800s, the formulation of national principles was part of the process of negotiating what constituted China and who the Chinese people were. The concepts of ethnicity and nation developed at the intersections between Chinese state’s relations with its domestic Others and its turbulent interactions with the outside world. The themes of national survival, territorial unity, cultural cohesion, stability of borders, and the development of the Chinese nation into a strong modern state are closely related to the formation of the politics of ethnic and national identity.
