A key challenge for the party since 1949 has been to forge a new Chinese nation within the boundaries of a vast, ethnically heterogeneous former empire. The party has experimented with a variety of policies and mechanisms for securing the loyalty and obedience of non-Han groups, shifting between accommodative and assimilative approaches depending on the broader political climate at any given time. Frustrated by continued ethnic unrest, which the party sees as a threat to social stability and its political legitimacy, the party has, in recent years, sought to fortify the unity of the nationalities via increasingly coercive administrative and technological measures. This chapter examines the coercive measures implemented by the CPC to guide and control China’s minority nationalities. These include controls over religion, language, traditional practices, minority nationality regions, and minority nationalities who ventured to other parts of China. The controls are designed to prevent ethnic protest and to forge a common Chinese ethnic identity that subsumes all other ethnic identities and which is united by loyalty to the party-state.
