Abstract: Unity is the opposite of separatism and it is a long-term arduous process. Taking unity their goal, the rulers of the Qing dynasty were adept in dealing with the contradiction between unity and opposition, and in seizing the opportune moment to unify the country. They suppressed separatism and effectively extended their jurisdiction and sovereignty over the border areas, thus unifying the country. The unity of the Qing dynasty was the wish of all nationalities in the border areas and it gave a great impetus to the consolidation and development of the unitary multi-national state of China.
