The Archdiocese of Moscow administers the Latin Rite of the Catholic Church in Russia. Further suffragan bishoprics exist in Irkutsk, Novosibirsk and Saratov. The Diocese of Irkutsk is in fact the largest Catholic bishopric on earth, covering an area of 9,960,000 squared kilometres. Almost all Russian Catholics adhere to the Latin Rite. However, the Catholic Church recognises the extremely small Russian Greek Catholic Church as a Byzantine Rite church "sui juris" ("of its own jurisdiction") in full communion with the Catholic Church.
