Max Verstappen won his first world title in controversial circumstances.
The Abu Dhabi Grand Prix is tarnishing the image of the sport according to the governing body.
The teams and drivers will be given a detailed analysis and clarification exercise by the FIA, which will give them any lessons from the situation.
It is an admission of mistakes made in the race that decided the world championship.
Michael Masi's actions are at the center of the controversy.
The Australian did not follow the rules when restarting the race after a safety-car period, but he was not mentioned in the statement.
Lewis Hamilton, who had led for the majority of the race and was on course for the world title, was left sitting on old tires by Masi, with Max Verstappen's Red Bull behind him.
The race was stopped for one final lap and the Dutchman passed Hamilton to win the drivers' title.
The statement looks to be an olive branch to Mercedes, who have announced they intend to appeal against the decision to reject their initial protest.
Since the race, Mercedes have been in talks with the FIA about what happened.
Mercedes have until Thursday to make a decision on the appeal.
Verstappen said they sometimes hated each other.
Verstappen thinks races should be won on the track.
What will the FIA do?
The World Council of the F1's legislative body was held on Wednesday.
The circumstances surrounding the safety car and communications between teams and Masi had caused significant misunderstanding and reactions from Formula 1 teams, drivers and fans.
The argument that Masi let some cars unlap themselves and did not comply with rules about the timing of the restart of the race was tarnishing the image of the championship and the due celebration of both.
It promised that "clarity would be provided to the participants, media, and fans about the current regulations to preserve the competitive nature of our sport while ensuring the safety of the drivers and officials".
It would be done in time for any feedback and conclusions to be made before the beginning of the season.
At a news conference on Wednesday at Red Bull's UK F1 headquarters, Verstappen and Red Bull team principal Christian Horner said Masi needed more support to be able to do his job effectively.
It's unfair to hate on Michael because he's a nice guy and he tries his best, it's a very tough job.
Michael has been under a lot of pressure.
After the Saudi Arabian Grand Prix, which was the last race of the season, F1 was missing the late Charlie Whiting, who was the race director, according to Christian Horner.
"You have to remember that Charlie had a former deputy race director sitting next to him," he said. They were doing two things at the same time.
It's a little unfair that he's up there on his own. He doesn't have anyone to support him.
The level of data and information that teams have available to them is immense and I think that the lesson from this season is: How can we do a better job? How can the FIA do a better job?
Was there any other World Council decisions?
The new engine formula will be introduced in 2026, and more clarity on the plans for it was provided by the FIA.
The hybrid part of the engine will have more than double the energy of the current 160 kilowatts.
The MGU-H, the part of the hybrid system that recovers energy from the exhaust, would be removed.
A cap on engine costs will be introduced.
The new engine formula would aim to ensure a powerful and high-revving power unit, car performance, sound, and drivers' ability to race, avoiding excessive differentiation.
