Their vaccination rate among elderly is quite low, their vaccine isn't as good as the main Western vaccines, and their hospital system in rural areas isn't very good. If/when COVID runs rampant they will have a lot of deaths. That's a particularly big problem given the upcoming Party congress where Xi will be crowned as dictator-for-life.
When is the Party congress? Can it happen that, after the congress, they let the Covid run rampant, to get rid of the elderly and have better figures for a few years after that?
