Help me block China

Our small company email server (and hence, our network) is hit regularly with Chinese hackers trying brute force attacks on accounts. In fact I would go so far as to say that 99% of attacks on our network originate in China.
Conceivably, I could create (or copy - I know there are sites that already list these) giant access lists for our Cisco ASA to block the entire nation of China but I'm not sure if this is the best approach. I assume our firewall will take a massive performance hit if I do this. Of course their regular, constant attacks are probably not helping performance or my time either.
Are there any other options besides ACL's or what do you do - or do you do nothing at all and rely on your users to create good passwords?
