"We understand that our fans were looking forward to another edition of the Singapore Grand Prix," said Colin Syn, deputy chairman of the race. And authorities there have decided their control measures are not compatible with thousands of people coming into the country for a grand prix. A revival of the Chinese Grand Prix, which was postponed from its early-season date this year, is also possible. If that happens, the first race would likely be on 15-17 October, the weekend before the US Grand Prix, which is on 22-24 October. However, the concern is around what would happen if there was a positive case among F1 personnel while they are out in Australia.
