On Monday China's regulator ordered all Chinese airlines to ground Boeing 737 Max 8 aircraft after crash in Ethiopia, which killed 157 people. Using these planes won't resume until "confirming the relevant measures to effectively ensure flight safety", the Civil Aviation Administration of China said in a statement.
China added it would revisit the situation after consulting with Boeing and the U.S. Federal Aviation Administration (FAA).
Indonesia also grounded all 737 Max 8s to ensure safety. The first catastrophic 737 MAX crash happened in Indonesia, operated by Lion Air and killing 189 people on board.
"Although we don't know the cause of the crash, we had to decide to ground the particular fleet as extra safety precaution," Ethiopian Airline said.
Cayman Airways grounded both of its new 737 Max-8 jets temporarily too, while India announced a safety review.
The Boeing 737 MAX has been flying for less than two years. Boeing has delivered 350 MAX jets to airlines around the world since May'2017.
Boeing has already postponed the debut of its new 777X jetliner, which was scheduled for this week, following Sunday's crash that threatens the company's reputation for safety.
