F1 commercial boss Sean Bratches has written to Brazilian president Jair Bolsonaro in support of moving the Brazilian grand prix to Rio.
O Globo newspaper reports that Bratches also sent the letter to Rio de Janeiro governor Wilson Witzel and mayor Marcelo Crivella asking for meetings "in person or by telephone".
Apparently, moves are afoot to build a circuit in Rio that could replace the ageing Interlagos track in Sao Paulo.
The newspaper also said contact with the Rio authorities has been made by Dorna, the MotoGP owner, as well as F1 circuit architect Hermann Tilke.
The circuit is proposed for Deodoro, a neighbourhood in Rio's west zone.
Bratches said in Baku: "I can confirm the letter."
O Globo also quoted an official of a company called Rio Motorsports as saying: "If construction works are completed by September 2020, formula one competitions can take place there in November."
F1 chief executive visited Rio de Janeiro and met with city officials in November last year.
