The 1954 Geneva Conference agreements required the withdrawal of foreign forces, and allowed the Pathet Lao to establish itself as a regime in Laos's two northern provinces. The Viet Minh and North Vietnamese, in spite of the agreement, never really withdrew from the border areas of Laos and the Pathet Lao continued to operate almost as a branch organization of the Viet Minh. Two months after the conference, the North Vietnamese formed the unit Group 100 with headquarters at Ban Nameo. The unit effectively controlled and directed the Pathet Lao movement.
