Sums of Inner Mongolia

In Inner Mongolia, China, a sum or sumu is a township-level political/administrative division. The sum division is equivalent to a township but is unique to Inner Mongolia. It is therefore larger than a gaqa (village) and smaller than a banner (the Inner Mongolia equivalent of the county-level division). Examples include Shiwei, Inner Mongolia and Honggor Sum, Siziwang Banner.

Sum whose population is predominated by ethnic minorities are designated ethnic sum – parallel with the ethnic township in the rest of China. As of 2010, there is only one ethnic sum in China, the Evenk Ethnic Sum. The Enhe Russian Ethnic Township of Inner Mongolia is not called sum.
