Cham areas are remnants of the Kingdom of Champa (between the 7th and 18th centuries). The Cham people, or Urang Campa in the Cham language, is an ethnic group in Southeast Asia concentrated between Kampong Cham Province in Cambodia and central Vietnam's Phan Rang-Thap Cham, Phan Thiet, HCMC and An Giang areas. They form the core of the Muslim communities in Cambodia and Vietnam.
