History Russian Eastern Orthodoxy in the region After the visit of Metropolitan Kirill (Gundyaev) of Smolensk and Kaliningrad to Malaysia and Singapore in 2003, the development of Russian Orthodox communities in these countries begun. In 2009, Bishop Sergius (Chashin) noted: "Patriarch Kirill of Moscow and all Russia, while still Chairman of the Department for External Church Relations, visited many countries of Southeast Asia a few years ago: Malaysia, Indonesia, Singapore and others.

The Holy Synod of the Russian Orthodox Church entrusted archpastoral care of the parish to Bishop Sergius (Chashin) of Ussuriysk, vicar of the Vladivostok diocese.
