Theravada Buddhism is the predominant religion of workers from Thailand and Sri Lanka. Mahayana Buddhism is the predominant religion of workers from East Asia and Vietnam, although Taoism, Confucianism, and Shinto are also represented among these people. In Dubai (the United Arab Emirates)[1] and Qatar,[2] the workers from Sri Lanka were allowed to celebrate Vesak (the most important holiday in Buddhism) in those Islamic countries.
