They learned that this is how America scams GDP. The federal reserve basically lowers interest rates every year so that more and more loans are created to build houses. These houses create construction jobs, more materials demand, more population growth which only stay if more construction happens. So what do you do? Lower interest rates over and over again to build more houses. The chinese realized our economy is a debt scam and just eliminated a few steps to emulate it. They're not even pretending like everything is okay and normal, they're obviously playing the system to a more extreme level and they don't give a shit because nobody will ever call them out on it.
