An insurgency was waged by Montagnards in FULRO against South Vietnam and then unified Communist Vietnam. A settlement program of ethnic Kinh Vietnamese by the governments of the Republic of Vietnam and the Socialist Republic of Vietnam was implemented and now a Kinh majority predominates in the highland areas. After mass demonstrations and protests during 2001 and 2004 by ethnic hill tribe minorities against the communist government, foreigners were banned from the Central Highlands for a period of time.
