They've had regular city-wide/regional lockdowns all throughout. If someone in your apartment complex tests positive SURPRISE you cant leave for two weeks. Normal is gone, it's not coming back. When you move the goal post from "not overwhelming our medical system" to attempting "covid zero" this is the new normal you end up with, somewhere between China and Australia.

Right now it seems quite the opposite. Their vaccines are not very effective against the Delta variant, and they're having several outbreaks. They recently shut down a huge port. They never learned how to do partial lockdowns and just dealing with low levels of infection, so if they don't manage to eliminate the virus, they're screwed. What are they going to do with the Delta variant? Import foreign vaccines? Wait for better domestic vaccines? What if a new more infectious variant comes along that's even less affected by their vaccines?

I think China may be a case of the cure being worse than the disease. We know their approach has killed people, and the huge amount of resources spent on these lockdowns and massive amount of testing may have been better spent saving lives elsewhere. But we'll never know because they don't publish reliable data on excess mortality.
