Torrential rain meant the race didn’t take place, with two laps behind the Safety Car used by the FIA to determine the final result.
Max Verstappen was classified as the winner ahead of George Russell, who claimed his maiden F1 podium.
With half points handed out, it allowed Verstappen to reduce Lewis Hamiltons’ lead to just three points ahead of F1’s return to the Netherlands.
The Frenchman confirmed that the FIA will review the regulations after a number of issues cropped up throughout the weekend.
“This year’s Belgian Grand Prix presented extraordinary challenges,” Todt said in a statement released on social media.
“The weather windows predicted by the forecasters did not appear throughout the day, and while a small window did appear late in the day during which there was an attempt to start the race, conditions quickly worsened again.
“Therefore, due to the lack of visibility created by the spray behind the cars, we could not run the full race in sufficiently safe conditions for the drivers, marshals as well as the brave spectators who waited for many hours in the rain, for whom I am very sorry.
“The FIA, together with Formula 1 and the teams, will carefully review the regulations to see what can be learned and improved for the future.
“The findings, including the topic of points allocation, will be added to the agenda of the next F1 Commission meeting on October 5.”
