The Dehong Autonomous Prefecture has under its administration two cities, namely Mangshi city and Ruili city, and three counties, namely Lianghe county, Yingjiang county, and Longchuan county.

Ruili, situated in the southwest of Dehong, is the most western town in Yunnan province. Surrounded on three sides by Myanmar, Ruili is one of two first-class national border ports in Dehong.
