The rule of law can improve and guarantee grass-roots governance in ethnic minority regions. With acceleration of the rule of law in China, the grass-roots governance in ethnic regions has achieved some good results. But for various reasons, there still exist some problems with current rule of law process in ethnic minority regions, such as incomplete legal system, backward development of village-level party organizations, confused responsibilities of township governments and autonomous organizations, low legal quality of grass-roots governance team, and low rule of law awareness of some people. To further improve the rule of law in ethnic minority regions, China should refine the legal system, strengthen the village-level party organizations, clarify the respective responsibilities of township governments and autonomous organizations, strengthen the building of grass-roots governance team, and raise the rule of law awareness of the masses.
