"Although we don't yet know the cause of the crash, we had to decide to ground the particular fleet as extra safety precaution," the airline said.
Ethiopian Airlines has a fleet of four 737 MAX 8 jets, not counting the one that crashed on Sunday, according to flight tracking website FlightRadar24.
China on Monday ordered its airlines to suspend operations of their 737 MAX 8 jets by 6 p.m. (1000 GMT) following the crash in Ethiopia, the second of a Boeing 737 MAX jet since one operated by Indonesia's Lion Air crashed in October.
