The Constitution provides for freedom of religion and for the principle of separation of church and state; however, the Government continued to restrict these rights in practice. The Government permits the operation of what it considers mainstream religious groups, including approved Muslim groups, Jewish groups, the Russian Orthodox Church, and various other Christian denominations, such as Roman Catholics, Lutherans, and Baptists. Uzbek society generally tolerates Christian churches as long as they do not attempt to win converts among ethnic Uzbeks; the law prohibits or severely restricts activities such as proselytizing, importing and disseminating religious literature, and offering private religious instruction.
