The problem is that manufacturing is in a large part going to automation. And China is no longer the low cost centre it was. It's too late. Big companies looking to the next low cost centres. I can tell you salary inflation in Shenzhen runs at 8 or 10 percent , maybe more. I know people who have to move every year or so further and further away from the centre as rents are increasing at stupid rate as well.
If you think Manufacturing is going to come back to the US in huge amounts because of what he's going you're very wrong. Not going to happen. What might happen is more sub assembly finishing as many markets moving to more tailored finishing with standard components allowing for speedy delivery to market.
I was shocked when I went. China's supposed to be communist? Well it's not. It's a single party capitalistic bear-pit. Great Dim Sum though.
The problem with China is/was intellectual property. They're shocking and that does need standing up against.
