VT5-U unmanned demonstration vehicle makes an appearance again at the Zhuhai Airshow. Basically, the developer integrated a remote operation system into a regular VT5 light tank. The system itself is platform agnostic and can be integrated into other vehicles.
I haven't come across a dedicated thread for it either. As for the 105mm gun, it's hard to say for sure, but given the design of some Norinco prototypes, there's a chance it could be rifled for improved accuracy. Would be interesting to see more details on this one!
All of the recent ZTQ-15 pics released within the last year or 2 featured the 'complete' configuration(ERA + CITV), no more 'poverty package'. Seems like the PLA prefers it that way.
