Top spam hosters, how to decline email mentioning them

I was looking at this article

  http://en.wikipedia.org/wiki/E-mail_spam

It claims that "only five countries are hosting 99.68% of the global spammer websites", of which the foremost is China, hosting 73.58% of all web sites referenced within spam.[30]

I already refuse all email coming from China (and Korea). Never regretted this.

Now, I also want to ignore all emails mentioning all China and Korea hosted websites (not just .cn, but also .coms and so on that have Chinese IPs).

I will have to not do so with Russia hosted sites, due to me being a Russian by origin.

Is there some tool that I could use to accomplish that?

thanks
