I dont know why youre so hung up on “not enough supply for China”. There is no binary option. They could have imported multiple vaccines (like Vietnam and many other countries did) and used what they imported.
They didnt.
Instead they used their home grown vaccine which had terrible efficacy.

Vaccinating 20% of your population is not helpful. You need to hit 50-80% else you shouldn’t do it.
Supply being one problem and uptake being the other. Meant China never had a proper “opening up” option presented.
That, coupled with the fact that the Chinese population have resisted getting vaccinated meant that it was never a viable strategy to purchase billions of doses and open up. The only option they had was COVID-0 style strategies.
