You don't have any say, so you shouldn't hold your breath. The books there seem to be mostly print. Since Amazon bought it's way into an existing business, it's not a huge surprise that it's overwhelmingly geared towards consumer electronics.
CF, amazon.cn doesn't sell e-books and may never do so. It has nothing to do with Amazon, everything to do with CN.
If you have print editions, they may well show up on CN after a time, sold by third-party Marketplace sellers. I see nine of mine up there, though several of them are out of print editions. (And of course, like all Marketplace offerings, the seller may not actually have a copy but is hoping he can find one if he gets an order.)
I don't see any logic in the way they're listed, certainly not by sales as they tend to be in the US store. Some have Amazon.com reviews attached, in English.
