Jackie Chan called the US the most corrupt country on the earth.
Judging by all the many Chinese products that have injured, sickened and killed adults and babies because of the corruption of those making the product, I'd say China is much more corrupt than the US.
How so? I think there is a big difference.
In the USA, a company can make 3 Billion in profits from knowing selling products that injure, sicken, or kill. When they get caught, in the USA, they will receive a 2 million dollar fine payable to the government regulators imposing the fines (not to the victims) less than 1% of their profits.
In the USA, bankers can rip people off and destroy an economy in the process, and in exchange they get bailed out or regulators look the other way. In China, they get the death penalty.
