Sao Paulo governor Joao Doria says Formula 1 is staying at Interlagos.
In recent weeks, the race beyond 2020 has seemed endangered after Liberty officials met with counterparts in Rio de Janeiro. Brazilian president Jair Bolsonaro has even said a switch to Rio is "99 per cent" certain.
But Sao Paulo governor Doria told Terra: "Formula 1 will not leave Sao Paulo.
"Rest assured it is remaining here.
"There was a lot of desire from Rio to have Formula 1, but it will not leave Sao Paulo. We will not allow that to happen.
"We are making a deal with Liberty so that F1 will continue to be here," Doria added.
