Formula One will have a four-week hole in this season's calendar after the sport's bosses confirmed the Chinese Grand Prix would not be replaced.
The race in Shanghai – which had been due to take place on April 16 – was cancelled last month amid ongoing coronavirus restrictions in the country.
Despite Chinese officials subsequently moving away from their zero-Covid policy, the round could not be salvaged, marking the fourth season it has been scrubbed from the racing schedule.
F1 executives assessed a number of options to fill the vacant slot, with Portimao in the Algarve understood to be the main contender.
But the sport's chiefs decided against the logistical headache of diverting to Portugal following the third round of the season in Melbourne, Australia on April 2, and then on to Azerbaijan.
It is believed F1 explored the opportunity of bringing the race in Baku forward by a week, but it was confirmed on Tuesday that the fixture on April 30 will not be moved.
The season begins in Bahrain on March 5, concluding in Abu Dhabi on November 26 and features a record 23 rounds, one more than last year.
F1 said in a statement: "Formula One can confirm the 2023 season will consist of 23 races. All existing race dates on the calendar remain unchanged."
The grid's 10 teams will unveil their new machines next month ahead of the sport's sole pre-season test which takes place over three days in Bahrain, starting on February 23.

When does pre-season testing take place?
Unlike last year, there is only one pre-season test before the 2023 season. That runs from Thursday February 23 until Saturday February 25 at the Bahrain International Circuit, just outside of Sakhir.
What are the 2023 car launch dates?
Red Bull, RB19: February 3, New York
Williams: February 6, online
AlphaTauri AT04: February 11, New York
Aston Martin AMR23: February 13, Silverstone
Ferrari: February 14
Mercedes W14: February 15, Silverstone
Alpine A523: February 16, London
Alfa Romeo: February 7
When is the first race of 2023?
The first grand prix of the 2023 season is also at the Bahrain International Circuit, running from Friday 3 until Sunday 5 March.
Where and when will the six sprint races be this year?
Formula One has announced the six sprint venues for 2023 with Azerbaijan, Belgium, the Austin race in the United States and Qatar all joining Austria and Brazil in staging qualifying on Friday and a shortened ‘sprint' race on Saturday.
Three sprint races were held in 2022 – at Imola, Austria and Brazil – with much discussion in the early part of the season about expanding that offering for next year.
The teams and F1 were keen to double the number, arguing that sprint races have been successful in engaging fans and increasing audience sizes. But the FIA, motorsport’s world governing body, initially resisted, claiming that it would cost them more and asking for compensation.
Like last year, too, points will be given to the top eight drivers in the sprint race. Again, the sprint races will be approximately 100km – or roughly a third of a grand prix distance – and will run on Saturday, with the traditional three-part qualifying setting the grid for the sprint and taking place on the Friday.
The driver who tops qualifying on Friday, when these sprint races take place, will be awarded the official pole position, not the winner of the sprint, as was the case in 2021.
What are the driver line-ups?
Red Bull: Max Verstappen (33) and Sergio Pérez (11)
Mercedes: Lewis Hamilton (44) and George Russell (63)
Ferrari: Carlos Sainz (55) and Charles Leclerc (55)
Alpine: Esteban Ocon (31) and Pierre Gasly (10)
