ASEAN has renounced the use or threat of force as a mode of managing relations between states. It has opposed invasion and occupation as a way of bringing about change in neighbouring countries. In line with this position, ASEAN took a leading role in bringing about a political settlement of the Cambodian conflict of -1979-1991. Following the settlement, ASEAN brought all the states of Southeast Asia into one regional association, thus healing the division of the region.
