Freedom of religion in Bhutan
The Bhutanese Constitution of 2008 and previous law provide for freedom of religion in Bhutan; however, the government has limited non-Buddhist missionary activity, barring non-Buddhist missionaries from entering the country, limiting construction of non-Buddhist religious buildings, and restricting the celebration of some non-Buddhist religious festivals. == Overview == Drukpa Kagyu (Mahayana) Buddhism is the state religion, although in the southern areas many citizens openly practice Hinduism.
