This is the second week China has been back to work. So, is OP saying the the Chines have decided not to continue supplying parts and materials to the US? I have been dealing with China for the last twenty years, especially, companies from Chengdu. Companies started sending out notices that they went back to work last week. Okay, they still have pockets of crap to deal with, but the Chinese people have been returning to work. The virus is not decimating their society so now they don't want to sell products into the US?
