Ch'à Ânnae County is a kun, or county, in Kangwà Ân province, North Korea. Originally part of Munch'à Ân, it was made a separate county as part of the general reorganization of local government in December 1952.
Ch'à Ânnae borders the Sea of Japan (East Sea of Korea) to the east. Most of the terrain is mountainous, but there is level ground near the coast in the northeast. The chief stream is the Ch'à Ânt'an River (ì²ÂÃÂÂê°Â). The county's area is roughly 70% forestland.
Ch'Ã Ânnae county is divided into 1 Ã Âp (town), 3 rodongjagu (workers' districts) and 15 ri (villages):
In the northeast, the dominant industry is agriculture. The chief local crops are rice, maize, and soybeans; sericulture (silk farming) and orcharding also play a role.
Mines extract local mineral deposits including limestone and anthracite.
The Kangwà Ân Line of the Korean State Railway runs through Ch'à Ânnae county, with a short branchline connecting Ch'à Ânnae-à Âp to the mainline. The county is also served by roads.
