Carlos Slim Domit has confirmed efforts to revive the Mexican Grand Prix.
On a visit to Mexico last week, and before touring the Hermanos Rodriguez circuit, FIA president Jean Todt said it is "possible" the country will return to the F1 calendar.
"It is being studied," businessman Carlos Slim Domit, the son of the world's richest man Carlos Slim Helu, is quoted by the Europa Press (EP) news agency.
The report said Slim Domit, whose father controls the Sauber and Sergio Perez sponsor Telmex, is on the FIA's ten-member senate.
He reportedly said officials of the sport are working on the project to end Mexico's 20-year F1 absence along with the Mexican entertainment company CIE.
CIE is the operator of the Hermanos Rodriguez track in Mexico City, the scene of the last Mexican grand prix in 1992 won by Nigel Mansell.
Slim Domit said the circuit is one option for future Mexican Grands Prix, but EP said the facility would require "large investments" for improvements.
He said another option is a street circuit in the western city of Guadalajara.
Europa Press said CIE did not immediately comment.
Rosberg vows to 'wait' for winning Mercedes
Nico Rosberg has admitted he has had to delay for now his hopes of becoming a GP winner.
The German driver, who contested his 100th F1 race in Hungary, said in an interview with Spain's El Pais: "No one could win with my car.
"There are three teams - Red Bull, Ferrari and McLaren - who are ahead of the others. I need to wait to get a better car.
"Later this year or early next year I will start to think about winning," said Rosberg.
Mercedes GP entered the 2011 season with high hopes, but Auto Motor und Sport reports that the Brackley-based team has now acknowledged that key technical aspects were flawed.
For instance, the W02 car has recently switched to a Red Bull-like exhaust/diffuser layout, while boss Ross Brawn admitted that for 2012 "we will build a longer car".
Rosberg's goal for now, then, is to finish just behind the aforementioned three teams at grands prix.
"With this car, to me seventh place is like winning," said the 26-year-old.
Asked which areas of the car need to be improved, Rosberg added: "Everything. In general it's the aerodynamics, mechanically in terms of reducing weight.
"The engine is fine," he continued, "but the blown exhaust system, which is a very important part of the aerodynamics now, can be improved a lot. We're working on it."
Di Resta's manager Hamilton hints at Mercedes 'interest'
Paul di Resta's manager has hinted Mercedes could be interested in signing the rookie Scot for 2012.
The comments by Anthony Hamilton on Tuesday follow Michael Schumacher's reported admission in the Italian press this week that he is not sure "if my mindset is right for this team".
"At some point we will evaluate whether I continue or stop," said the seven-time world champion.
Should the German return to retirement, di Resta - impressive on his F1 race debut with Mercedes-powered Force India this year - is considered the favourite for the seat.
He won the DTM championship with Mercedes last year and remains close to the German carmaker.
Said di Resta's manager Hamilton, the father of 2008 world champion Lewis: "I'd like to think that there is an interest - Paul is a Mercedes protege."
"I'm proud of him. He will make a great replacement for someone at a top team."
