You are going to struggle with that. You could start by asking what percentage of the components in your phone, i-Pad, computer, or whatever is your electronic medium for your daily ops-normal internet tipple, was sourced from China!
The Chinese have prospered due to our greed and shortsightedness, as we are always happier to go for the cheapest price and sanctifying the notion of maximum profit to the senior management and investors in our multinationals and big corporates, allied to our insouciance when it comes to paying a decent wage to workers, worrying about their health, safety and well being, particularly when they are "foreigners" like the Chinese are.
The USA has also needs China to buy US government bonds so that it can continue to borrow to run up its incredible national debt to fuel our seemingly insatiable need for all the gegaws that a consumer capitalist society maintains are required for happiness and thus it turns to China to make those gegaws on the cheap to maximise profit for the few. The Chinese need this arrangement too, to employ their vast population governed by an onerous totalitarian government, terrified that it will lose control if people aren't employed and so, perversely, both the USA and China are like two mad drunkards propping each other up at the last chance solution, mutually loathing each other but desperately also needing each other.
