Chinese airlines have been ordered to suspend Boeing 737 Max-8 flights after a deadly Ethiopian Airlines crash using the same model.
Domestic airlines must halt commercial operations of all Boeing 737 Max-8 planes by 18:00 local time (10:00 GMT), the aviation regulator said.
The Ethiopian Airlines flight crashed minutes after takeoff on Sunday, killing all 157 people on board.
It was the second crash involving a 737 Max-8 in the past five months.
In a statement, the Civil Aviation Administration of China said it would notify airlines as to when they could resume flying the Boeing jets.
