The Azerbaijan government is not sure that it will agree to a new race deal with Formula 1 chiefs.
Baku hosted its first race on the historic city streets in 2016, with the contract having been negotiated with the now former F1 supremo Bernie Ecclestone.
Now, sports minister Azad Rahimov is planning to stage talks with Liberty Media after this year's race.
"Within three months after the grand prix, we must give an answer to the leadership of Formula 1 about whether we will extend the contract for another five years until 2025," he told Tass news agency.
"Everyone understands that the contract we have now is unacceptable. I think the new leadership of Formula 1 understands that as well.
"We are talking about a number of commercial conditions, sponsorship rights and the price that we pay. But I think both ourselves and the leadership of Formula 1 have the desire to leave the race here."
The 2018 Azerbaijan Grand Prix takes place on April 29.
