China cares more about protecting the homebuyers and contractors who are building the homes more than protecting the investors [0][1]:
> Evergrande has almost 800 projects across China, many of them funded by advance payments from homebuyers.
> Local governments have ringfenced homebuyer deposits and other funds to ensure that Evergrande projects in their jurisdiction are completed and contractors paid on time.
So this is a much different reaction than the US government who protected the investors and banks.
