The Civil Aviation Administration of China said the order was issued at 9 a.m. Beijing time Monday and would last nine hours.

It said the order was taken out of safety concerns because the crash was the second after another of the planes fell into the ocean off the coast of Indonesia in similar circumstances on Dec. 29, killing all aboard.

It said further notice would be issued after consultation with the U.S. Federal Aviation Administration and Boeing on safety measures taken.

Eight Chinese nationals were among the 157 people aboard the plane when it crashed Sunday shortly after takeoff.

Boeing's newest version of its most popular plane is again in the spotlight after a deadly accident in Ethiopia.

A Boeing 737 Max 8 operated by Ethiopian Airlines crashed shortly after taking off Sunday from Addis Ababa, killing all 157 people on board.

The plane was new. The weather was clear. Yet something was wrong, and the pilots tried to return to the airport. They never made it.

Those circumstances make the accident eerily similar to an October crash in Indonesia that killed all 189 people on the plane.

Safety experts are noticing the similarities but say a verdict on the plane should wait until investigations are complete.

Boeing says its plane is safe. The company's sales didn't suffer after the Indonesia crash, and its stock price has soared.
