The varying experiences of different minority groups in China's Yunnan province are analyzed in light of the power resources that each possesses. The size, location, and impregnability of the group account for whether or not it can exert leverage on the regime in attempting to obtain cultural, political, and economic benefits. The author found that a group's assimilability, or its propensity to change its cultural traits, is negatively correlated with its numbers, with living in an isolated territory, and with its impregnability. The treatment the group has received under the People's Republic is dependent upon the same three power resources, as affected by the regime's policy and goals. For example, efforts have been made toward the political integration of groups whose main power resource is numbers, while the regime's main goal, when faced with groups whose principal resource is impregnability, has been to maintain civic peace.
