Hi, Swinehund, from your reply i can say you are financially and economically illiterate. Just check how much the US own China and the amount US bonds that China holds. Then you may suggest that China as the second economy had a lot of power on the global finance and economy.
Having said that Chinese labour market is heavily dependent on the US imports. This is huge Chinese economy's weakness. It estimated more than half billion Chinese farmers or residents from rural areas move to big manufacturing cites. So China also needs the global economy, especially the US market to prevent another peasants revolution in China. So this mutual needs from both the US and China keeps everything in balance.
However, the rapid expansion of AI and automation ( robotics) may affect this balance in favour of the US and other developed countries. Translation: when GM or Ford or Benz or Honda can use robots to manufacturer their products, the cheap labour in China and other Asian countries will be less attractive: Robots work 24 hours, they need no holidays or vacation, they not get tired or injured, they do not have families and most importantly their products' qualities will be the same ( no fatigue to affect the quality).
That's one of the reasons, Chinese smartly and heavily started to invest on the future economy: data economy.
