You may believe... but are you *sure*?  (Over the years, we've seen
*lots* of "block China" lists that accidentally block chunks allocated
to Taiwan or Australia or other Pacific Rim destinations).


If you really wanted to go the route of blocking all/almost all China. Isn't there a short list of ASNs that provide transit to China citizens/networks?
I'm referring to AS4134, AS4837, etc
Wouldn't blackholing any prefix with those ASNs in the AS path accomplish the goal and stay up to date with a new prefixes originated from China?
