Pearic peoples refers to indigenous groups, including the Pear, Chong, Samray, Suoy and Sa'och, which speak one of the Pearic languages and live a sparse existence after years of conflict in Cambodia and Thailand. Pearic groups speak different, but closely related, languages and share many cultural traits that differ markedly from the dominant Khmer and Thai cultures.
