Just as a side note, to complete the picture:  if an ISP has sufficient
customers (or a sufficiently large deployment plan), even larger address
blocks than a /32 can be allocated by the regional registries.

Currently, most ISPs do not need more than a /32, but at least in RIPE
land, one /31, /27 and even one /20 have been allocated to big Telco-ISPs
(with many broadband customers).

The same rules apply to APNIC ISPs, so "getting large enough address space" 
for chinese ISPs is mostly a question of actually talking to APNIC and
explaining their deployment plans.

For details on the APNIC IPv6 allocation policy, please see:
