Hi,
if he republishes your content, he breaches your copyright. Period.
Check the TOS of his host, if it contains a "no copyrighted material" clause, send the host another complaint. Don't do it by email, print it out just nicely on paper, make it serious in tone and look, include a threat regarding copyright infringement fees (or whatever else your own country's legislation proposes for such an offense) to be slapped onto the host if he does not comply within the next (your choice of time) days and send it first as a fax and parallely as a snail mail letter (with receipt).
At the same time, I'd try to find out who is setting up that host with a backbone connection. Maybe - if you're lucky - he is a reseller anyway, or co-hosts. It is my personal experience, that practically all western backbone companies also have a strict and active TOS where it comes to illegal matters such as copyright or porn. They force hosts set up with them to sign these on contract and they can force a host to comply with their own TOS if the host doesn't enforce it with his clients. Usually a mild reprimand by a backbone provider suffices completely to take any recalcitrant host to task.
I use this policy now for more than half a dozen years whenever I see instances of copyright infringement of my work or work of my clients, though mostly it's pictures, stories and art, not blog posts, and this very quickly sees results. When they get snail mail and have to sign for it, they usually take it seriously, and they sure as hell take a threat of loss of backbone connection seriously.
There are different ways to deal with eastern country infringements (which you don't want to know *VBEG* )...
