Great, I'll move it to the "Domain Appraisals" forum
.cn is still a hard extension to appraise, but "require" is a good keyword for sure.
Without knowing if you had any specific use in mind for the domain, I would say $15 - $20 at current market conditions. (Secondary Market sales of .cn's are lacking).
This might be one that requires a long term hold to gain any meaningful value.
