The constitution does not name official state religion, and provides for freedom of religion. Even the authority formally does not register new religious groups that have not been accepted and limit the number of missionaries, unregistered religious organisations as well as missionaries who are allowed to operate freely. There have been no widespread reports of societal abuses or discrimination based on religious belief or practice. Thai law officially recognizes five religious groups: Buddhists, Muslims, Brahmin-Hindus, Sikhs, and Christians. However, some laws are inspired from Buddhist practices, such as banning alcohol sales on religious holidays.
