Under the unified leadership of the state and under the principles of equality, unity, mutual assistance and common prosperity for all ethnic groups — autonomous agencies of self-government have been established wherever national minorities live in compact communities. Minority people exercise autonomous rights, are masters in their own areas and administer their own internal affairs. The Central Government actively aids the ethnic autonomous areas with funds and materials to promote the development of the local economies and cultures. The Law on Regional Ethnic Autonomy adopted in 1984 at the Second Session of the Sixth NPC is the basic law specifically guaranteeing that the constitutionally decreed regional ethnic autonomy system is carried out. Now apart from five autonomous regions (the Inner Mongolia, Xinjiang Uygur, Guangxi Zhuang, Ningxia Hui, and Tibet autonomous regions), China currently has 30 autonomous prefectures and 120 autonomous counties (known, in some cases, as “banners”), in addition to more than 1,300 ethnic townships. The agencies of self-government in ethnic autonomous areas are the people’s congresses and people’s governments of autonomous regions, autonomous prefectures and autonomous counties (banners). The chairperson or vice-chairpersons of the standing committee of the people’s congress and the head of an autonomous region, autonomous prefecture or autonomous county (banner) shall be citizens of the ethnic group(s) exercising regional autonomy in the area concerned. Agencies of self-government in ethnic autonomous areas enjoy extensive self-government rights beyond those held by other state agencies at the same level. These include: Enacting regulations on the exercise of autonomy and separate regulations corresponding to the political, economic and cultural characteristics of the ethnic group(s) in the areas concerned; having the freedom to manage and use all revenues accruing to the ethnic autonomous areas; independently arranging and managing local economic development, education, science, culture, public health and physical culture, protecting and sifting through the cultural heritage of the ethnic groups, and developing and invigorating their cultures.
