The Apostolic Administration of Harbin was erected on May 28, 1931. Archbishops Celso Costantini and Mario Zanin, Apostolic Delegates to China, had been its apostolic administrators successively.
After the founding of the People's Republic of China in 1949, all foreign missioners were expelled from the mainland. The Apostolic Administration of Harbin became a part of Harbin diocese when the government-sanctioned "open" Church structure created the new diocese by merging in Heilongjiang province in 1959.
Father Peter Wang Ruihuan became the first "self-elected and self-ordained" bishop of Harbin without papal mandate in the same year. The diocese was renamed as Heilongjiang diocese in 1983. Father Liu Huanbo was ordained coadjutor bishop of Heilongjiang without papal mandate in 1990 and succeeded Bishop Wang upon his death two years later. The diocese remained vacant after Bishop Liu died in 1997.After Bishop Liu died in 1997, the diocese remained vacant until 2012 when Father Joseph Yue Fusheng received episcopal ordination without papal mandate. He was subsequently excommunicated by the Holy See.
