Four new priests were ordained for the Diocese of Shanghai on June 5. But the ceremony illustrated the control exerted by Beijing, as the government blocked the ordination of a fifth deacon, because he had attended World Youth Day in Krakow in 2016. The ordinations were performed by Bishop Joseph Shen Bin, the vice-president of the government-backed Catholic Patriotic Association. Bishop Thaddeus Ma Daqin of Shanghai could not attend because he has been under house arrest since 2012, when he resigned from the Patriotic Association.
