What have China done?
Denied Covid was a thing.
Not stopped people leaving China as soon as they knew about it.
Crippled the entire world economy, except for one country.
Forced the WHO to completely change their view on how to behave in a pandemic (don’t lockdown, don’t do track and trace with large numbers of cases, for example).
In fact Sweden, far from ‘doing nothing’, actually followed the WHO guidelines almost to the letter. It’s quite an interesting read and it’s from October 2019.
