On 22 April 2010, 72-year-old Pierre Nguyễn Văn Nhơn, Bishop of Đà Lạt, was appointed Coadjutor Archbishop of Hà Nội by Pope Benedict XVI.

[3][4] There was well-documented evidence of tension between the Church and the government over the old apostolic delegation[a] building dispute in 2008.

The prime minister had promised to return the building, but after some protests in his Archdiocese at Thái Hà church and the delegate building, which ended in violence due to inference by "pro-government gangs," the building is still not returned and the government blamed the Archbishop as the culprit for the incident.

[5] The rumor goes that also in that year, the mayor of Hà Nội had asked for Kiệt to be removed as archbishop.

However, Kiệt denied these rumors publicly and that there was "no pressure from any side" but that he reportedly admitted to suffering from stress and insomnia.
