Red Bull advisor Dr Helmut Marko says China is currently the only “fixed” non-European race on the 2020 calendar.
So far eight rounds have been confirmed for the 2020 Formula 1 season.
It will start with back-to-back weekends in Austria, with the first race on July 5. A second round the following weekend preceds the Hungarian Grand Prix.
Two race weekends at Silverstone, and then the Spanish, Belgian and Italian GPs complete the confirmed European phase of the season.
After that the schedule is still very much subject to change, and Singapore, Japan, Azerbaijan and Australia are the flyaway races that have already cancelled their 2020 events.
