Islam in Vietnam is primarily the religion of the Cham people, a minority ethnic group related to Malays.
Roughly one-third of the Muslims in Vietnam are of other ethnic groups. There is also a community describing themselves of mixed ethnic origins (Cham, Khmer, Malay, Minang, Viet, Chinese and Arab), who practice Islam and are also known as Cham, or Cham Muslims, around the region of Chau Doc in the Southwest.
Vietnam's largest mosque was opened in January 2006 in Xuan Loc, Dong Nai Province; its construction was partially funded by donations from Saudi Arabia.
