China does not have a representative Government.
China does not have a private economy.
China does not have private intellectual property rights.
China's trading relationships are a Chinese Communist Party strategy to catch up economically and technically with the West via theft.
China's 'promise' of cheap labor, no environmental law impediments, no labor law impediments, and 1 billion new consumers - a manufacturing business utopia - is the lure for the West to sell China the rope which the Chi-coms will use to hang the West.
So, WTF was China allowed to join the WTO and to be been given Most Favored Nation trading status? Greedy, lazy, corrupt, short-sighted, and naeve American leadership? The same Big Tech kleptocratic oligarchs that are 'shocked' that Trump is imposing tariffs? They are dumb or selectively willfully blind.
