Well I don’t know about Chinese leader but I know of one leader in history who did exactly that and was situated a little further north of China.Canada announced auto tariffs of 25% on the US. Not too significant since its only on non-CUMSA compliant vehicles, and they'll likely cave at the first sign of pusback.
Let's fire the academics and intellectuals and make them work in the steel factories... which Chinese leader said that before?
Now I get why Trump seems so fond of Putin and by extension the Motherland.
