Well, I'm not a China basher. I don't see what I want from particular sellers with lots of feedback, but they exist. China to me, is in a transitional phase where some manufacturers are seeing money to be made in higher quality items in exports.
If you were to look at the amount of Chinese, it could be assumed that some are tired of making shit products and would like to take a bit of pride in what they do.
All that said, if you know of genuine nihonto worth paying attention to, I'd appreciate it as much.
