As an economic entity China has a ton of submerged problems and I don't think their 'solutions' to any problem will easily transplant to the rest of the world without accepting a bunch of their other problems into the package as well.
It happens also in Hong Kong as well and is an intentional policy of the government. There is also a small HKD$1000 per month and is only intended as a subsidy. I note Hong Kong has one of the lowest personal income tax rates in the world.
