It appears the possibility of a South African GP is going to be thwarted again, but this time not because of money, but because of South Africa's relationship with Russia, and their unwillingness to condemn Putin.
This means that Spa will most likely remain on the calendar ... for now. There is still talk about alternating Spa with another race, most likely Zandvoort, in the future.
China is expected to be back in 2024, as they still have two years remaining on their contract. The circuit will first have to go through another inspection, as it hasn't been used for so long.
Speaking of China, the Macau GP is returning to being an international event this November. The international F3 race will return along with the GT World Cup. The past two years, the Macau GP was run, but "relegated" to being a local, regional event only (essentially just China, Hong Kong, and Macau drivers and teams) as it was nearly impossible for international competitors and teams to be able to meet the travel and quarantine rules. This is one event which has always been on my bucket list to attend.
