The Constitution of China guarantees freedom of religion for citizens, as it does the freedom of speech. In practice, however, there are strict regulations on religious practice and speech. Five state religions are officially recognized: Buddhism, Catholicism, Daoism, Islam, and Protestantism; faiths outside of these are illegal, although some are tolerated to varying degrees. The Church of Jesus Christ of Latter-day Saints, for instance, is permitted to maintain a small number of places of worship for expatriates, is forbidden from preaching or proselytizing to Chinese citizens, as are all foreigners. Foreigners caught proselytizing have been arrested and expelled from the country.
