Interesting test tank, but I doubt the PLA would be interested much.
One of the top feedback criticisms of the Type 99s are their cluttered roof. This left some blind spots for the commander sights that the PLA were not keen about. But you can see a clear effort to tidy that up as the 99s developed into the various subsequent blocks.
For this tank, The RWS, and especially the placement of the gunner sights would impose significant blind spots to the left and rare of the tank. I think that alone would rule it out for the PLA unless all its other stats are out of this world.
If I was to design a RWS, I would mount the commander sights above it on an independent gimble so you have a two layed system, with both able to operate independently if needed. This allows you to keep the same responsiveness as a normal scope, but with much better elevation and unobscured 360 view, as well as the benefits of the RWS.
The RWS and scope would operate like a miniture version of the hunter-killer system the commander has with the gunner. So if in the course of scanning around for targets, the commander spots a nearly infantry/light vehicle threat, you can set the RWS machine gun to lock with his sights and then be slaved to the scope with a single button push, allowing him to rapidly and accurately engage those targets.
