Buddhism came to Vietnam as early as the second century CE through the North from central Asia and via Southern routes from India. Buddhism in Vietnam as practiced by the ethnic Vietnamese is mainly of the Mahayana school, although some ethnic minorities (such as the Khmer Krom) adhere to the Theravada school. Buddhism in Vietnam has had a symbiotic relationship with Taoism, Chinese spirituality, and the indigenous Vietnamese religion. The majority of Buddhist practitioners focus on devotional rituals rather than meditation.
