It's worth noting that China doesn't have the outrageous interest rates we're seeing in the rest of the world. They're ~2.5% right now¹.

One reason for this is China has capital controls. You can't borrow money from a bank in China, and then dump it into an account in another country with a higher interest rate with no restrictions. Moving money out of China takes effort, so China can actually have their own monetary policy.
