With CIDR you can create the same number of addresses out of any of the traditional Class A, B, or C areas. There are plenty of /16 address blocks available. I have no idea of any need a country such as China has which couldn't be satisfied by using /16 CIDR blocks. If you stop thinking in terms of traditional classfull address blocks, I think you find much of the "scarcity" goes away.
