The State Council, China's cabinet, has set up an investigation team to probe the deadly quarantine hotel collapse in southeast China's Fujian Province which has killed 29 and left 42 injured.

On Thursday, the last person trapped under the debris of the collapsed hotel in Quanzhou City was retrieved and found dead.

The hotel collapsed on Saturday night in Licheng District, trapping 71 people underneath. Of them, 27 were dead when rescuers found them, while two others died after medical efforts failed.

A preliminary investigation found serious problems in Xinjia Hotel's construction, reconstruction, examination and approval stages, a local official told the media. 

An earlier report said the authorities will continue to investigate these stages, and why the hotel was chosen to be turned into a quarantine facility.
