The Vientiane Treaty was in some sense a corollary to the Paris Peace Accords, signed the month before, which had ended U.S. involvement in the Vietnam War.
Just as the Paris Accords had mandated the withdrawal of all US forces in Vietnam, the Vientiane Treaty called for the removal from Laos of all foreign forces allied to each side.
Under the terms of the treaty, a new coalition government was to be created; security in major cities (such as Vientiane) was to be undertaken by joint forces from both sides.
There were no outside guarantees to the terms, as the agreement was only between the Lao factions; the ICC (which had overseen the 1954 Geneva Accords ending the First Indochina War) was more powerless than before to monitor compliance.
