Yes the other possible strategy behind this is to hurt Western supply chains. Its no secret that the CCP has been waging a cultural propaganda war on the US and the West for a long time. So either the CCP is locking down SHanghai and other cities b/c their covid "experts" are a bunch of raving ignorant lunatic hysterics or they are playing economic and political games or some combo of both. Either way it doesnt look good for whatever group of fanatics is running things in the CCP
