The Vietnamese viewed and dealt with the indigenous Montagnards from the Central Highlands as "savages," which caused a Montagnard uprising against the Vietnamese. The Vietnamese were originally centered around the Red River Delta but engaged in conquest and seized new lands such as Champa, the Mekong Delta (from Cambodia) and the Central Highlands during Nam Tien. While the Vietnamese received strong Chinese influence in their culture and civilization and were Sinicized, and the Cambodians and Laotians were Indianized, the Montagnards in the Central Highlands maintained their own indigenous culture without adopting external culture and were the true Indigenous of the region. To hinder encroachment on the Central Highlands by Vietnamese nationalists, the term "Pays Montagnard du Sud-Indochinois" (PMSI) emerged for the Central Highlands along with the indigenous being addressed by the name Montagnard. The tremendous scale of Vietnamese Kinh colonists flooding into the Central Highlands has significantly altered the demographics of the region. The anti-ethnic minority discriminatory policies by the Vietnamese, environmental degradation, deprivation of lands from the indigenous people, and settlement of indigenous lands by an overwhelming number of Vietnamese settlers led to massive protests and demonstrations by the Central Highland's indigenous ethnic minorities against the Vietnamese in January–February 2001. This event gave a tremendous blow to the claim often published by the Vietnamese government that in Vietnam “There has been no ethnic confrontation, no religious war, no ethnic conflict. And no elimination of one culture by another.”
