I. IntroductionrnPrevalent globally, ethnic issue is related to world peace, national stability, social progress, the happiness of the people, and the prosperity and revitalisation of one country. Multi-ethnic countries are facing the same challenge of pursuing a harmonious relationship among multiple ethnic groups, while maintaining national unity, territorial integrity, and facilitating the free and equal development of different ethnic groups within their territorial borders. China is a multi-ethnic country which emphasises both pluralism and unity. After arduous trial-and-error practices, the Chinese Communist Party and the people of all ethnic groups throughout the country have explored the system of ethnic regional autonomy for its best suitedness for China\'s unique national conditions, which has been upheld as a basic political system in China. As concluded by the Fourth Plenary Session of the 19th Central Committee of the Communist Party of China, one of the 13 significant advantages of China\'s modernisation for governance system and capacity is its adherence to the equality of all ethnic groups, and its capacity to forge a sense of community of the Chinese nation, to achieve stern solidarity, and tomobilize the joint efforts of all ethnic groups for common prosperity.
