This is pretty much as expected but it may not happen as published as I think that one or two of the dates are going to be provisional. I am not sure how the Chinese are going to get everything sorted out by April because they were looking for an October date, to buy more time to get around all the COVID restrictions that are still in place.
From what I hear from China the procedures there are very complex and very difficult for visitors. All travelers currently need to quarantine at a government-designated location on arrival. While in quarantine, there are daily tests and anyone who tests positive will be transferred to a government-run medical facility.
At the same time lockdowns can occur at any moment and people can be stuck there for as long as the lockdown is deemed to be necessary. Perhaps arrangements will be made to make life easier for F1, and perhaps things will change, but at the moment this is the case.
There are a number of other issues with the dates published, including Monaco being in the middle of a triple-header not to mention a fairly brutal Austin-Mexico-Brazil triple-header at the end of the year.
