"Each government will make its own decision to return the aircraft to service, based on a thorough safety assessment," the FAA said in a statement.
The FAA has "set no time frame" for the aircraft's return to service, according to the statement.
FAA officials delivered the message to a group of 50 safety regulation officials from around the world, and also briefed the officials about the latest efforts to evaluate the safety of the Boeing 737 Max.
Concerns about Boeing's 737 Max aircraft were first brought to light in October last year, when a domestic Lion Air flight in Indonesia crashed into the Java Sea, killing all 189 people on board.
In March 2019, a second Boeing 737 MAX operated by Ethiopian Airlines in Africa and bound for Kenya's Nairobi went down shortly after takeoff, killing all 149 passengers and eight crew members.
With aviation experts around the world fearing the aircraft's newly installed Maneuvering Characteristics Augmentation System, which automatically lowers the nose of the plane in some cases, could be a fault, a number of countries took steps to ground the aircraft for safety concerns.
