IPv6 is the answer. The chinese already use it quite heavily, moreso than any other nation. Japan probably comes second.
The change could easily be driven by goverment policy. For example, the US gov makes a policy that all their workstations are IPv6 only. Contractors will immediately switch, subcontractors will switch, etc. The domino effect in action.
Sort of similar to how the US gov created the PC hardware and software industry by mandating that every gov employee have a computer at their desktop, therefore also fueling the massive growth of the internet.
