Border Security Command and Coastal Security Bureau are collectively responsible for restricting unauthorised cross-border (land and sea) entries and exits, in the early 1990s the bureaux responsible for border security and coastal security were transferred from the State Security Department to the Ministry of People's Armed Forces. Sometime thereafter, the Border Security Bureau was enlarged to corps level and renamed the Border Security Command. Previously headquartered in Chagang Province, the Border Security Command was relocated to P’yŏngyang in 2002.
