I dont think so, .cn is for china. And china has sub categorised their main TLD (something like sub-tld). You can even register ".com.cn", ".net.cn", or ".org.cn".
Well, if it's not a .edu then it doesn't count as one... All kidding aside, if you're asking as far as Google is concerned, only Google knows. (I'd tend to think maybe not.)
It is an educational domain from China. I do not know if .edu.cn is reserved for accredited educational institutions within China, but most countries have such a rule. So be careful what you do with it if you want to keep it. Also generally in China: Forbidden topics include pornography, gambling, violence, rumors and religion.
