Your source is about US media complaining that China isn't gonna pay their debt. In fact, if you actually read it, then you'll realize that it supports my point that US isn't actually in a position to do anything about it. That's literally what it's whinging about. China's financial position in the world comes from being the biggest trading partner for majority of the countries and producing most of the stuff people around the world consume. China doesn't need to protect assets on another continent because China is buying up commodities like gold that are kept in China https://oilprice.com/Metals/Gold/Chinas-Gold-Buying-Spree-Continues-For-Seventh-Consecutive-Month.html

In fact, US using the financial system it built is a weapons is precisely what's driving countries away from it right now. The whole system hinged on the idea that it was built on top of strong legal protections. Once US decided to steal Russian foreign reserves that demonstrated that it's a completely lawless system. The only legal paths towards seizing foreign reserves is a UN resolution or a declaration of war.

Meanwhile, and foreign borrowers are issuing a record amount of yuan debt, helping internationalize China's currency https://archive.is/A4kcO

And turns out you don't have to be an American to believe nonsense after all.
