Buddhism in Southeast Asia

Buddhism in Southeast Asia is mostly Theravadin. Vietnam however had in pre-Communist times a Mahayana majority due to Chinese influence. Indonesia was Mahayana Buddhist since the time of the Sailendra and Srivijaya empires but Mahayana Buddhism in Indonesia is now largely practiced by the Chinese diaspora, as in Singapore and Malaysia.

Southeast Asian countries with a Theravada Buddhist majority are Thailand, Cambodia, Laos and Burma.

Mahayana Buddhism with traditional Chinese religions such as Taoism and Confucianism (Ancestor Worship) is the predominant religion of mostly Chinese communities in Singapore where it's the largest religion, though it does not form a majority; while in Malaysia, Brunei, Philippines and Indonesia it is a strong minority. Vietnam continues to have Mahayana Buddhist majority to this day.
