China has the manufacturing capability to produce high end tanks on par with modern european / american standards, in sufficient numbers so I personally don't think it's wise to sacrifice capability for numbers. Perhaps a high-low mix like it currently is is a good trade-off. Should embrace new technologies. ERA/composites can be reduced, giving way to advanced APS, which ideally should be able to reduce the pen effect of even APFSDS. An iron vision system where the outside of the tank is projected via HUD or 360 LCD screens to give full situational awareness could also be beneficial. Drone RWS and jammers are a must-have. The only downside to this system is the overreliance on APS leaves the tank vulnerable to something like LOSAT, which is likely to re-emerge as the prevalnce of hard-kill APS increases.
