China is an irrelevant big factory, a big bubble without influence outside of Asia. What influence China has? Money? Ha, who needs em money, US fucking prints them lmao. Culture? I mean does China even have culture? They fucking copy Japanese anime, and still no one watches / reads that shit. Meanwhile the whole fucking world watches US movies, reads US books and listens to US music. Everyone in this fckn world works for American Entertainment.
China can be replaced by other big factories with cheap labor force like India, Bangladesh, Vietnam, Indonesia and many more.
And what about US debt? All those countries, including China are slaves of the US, they buy debt because this is the best investment you can make nowadays.
And no one can ask US to fully pay its debts, because US army is so great that China can lose 99% of its fleet in 1 day of naval battles.
