Article 10
The Commanders of the Forces on each side, on the one side the Commander-in-Chief of the French Union forces in Indo-China and on the other side the Commander-in-Chief of the People's Army of Viet-Nam, shall order and enforce the complete cessation of all hostilities in Viet-Nam by all armed forces under their control, including all units and personnel of the ground, naval and air forces.
Article 11
In accordance with the principle of a simultaneous cease-fire throughout Indo-China, the cessation of hostilities shall be simultaneous throughout all parts of Viet-Nam, in all areas of hostilities and for all the forces of the two parties.
Taking into account the time effectively required to transmit the cease-fire order down to the lowest echelons of the combatant forces on both sides, the two parties are agreed that the cease-fire shall take effect completely and simultaneously for the different sectors of the country as follows:
Northern Viet-Nam at 8.00 a.m. (local time) on 27 July 1954
Central Viet-Nam at 8.00 a.m. (local time) on 1 August 1954
Southern Viet-Nam at 8.00 a.m. (local time) on 11 August 1954
It is agreed that Pekin mean time shall be taken as local time.
From such time as the cease-fire becomes effective in Northern Viet-Nam, both parties undertake not to engage in any large-scale offensive action in any part of the Indo-Chinese theatre of operations and not to commit the air forces based on Northern Viet-Nam outside that sector. The two parties also undertake to inform each other of their plans for movement from one regrouping zone to another within twenty-five (25) days of the present Agreement's entry into force.
