Obviously, but the lists you link to use the same exact source.
If APNIC says it's China it's good enough for me.
Mainly because I get scraped and spammed from their neighbors as well :)
The only way to really refine it would be to make direct APNIC inquiries for all the ranges listed per country and examine them at a macro level and they'd most likely block me like LACNIC did for making too many requests.
Lucky for me I was using a proxy IP at the time...
