If we ignore geography and consider a hypothetical sandbox universe, I think China can fight and win wars that are within range with just drones alone. Not a single human soldier or pilot need to even be placed on field.
You have battery powered, rotor propelled drones with machine guns, rifles, grenade launchers numbering in the multi 10s of platform types and total numbers are in the 10s of thousands if you include modified commercial types. Robot dogs and unmanned ground vehicles equipped with everything from a rifle to 20mm, everything from anti-tank missile to short range air defence missiles. You have unmanned submersibles that can take out entire typical sized navies.
PLA is turning into a force where a single branch - PLA, PLAAF, PLARF, PLAN can individually defeat pretty much any military conventionally bar the US. PLARF now has enough ballistic missiles of every range and type that outnumber most militaries have armoured vehicles. PLARF fire off over a hundred SRBM to ICBM missile types in training every year and the factories are shown on satellite producing ballistic missiles like sausages. People even on this forum don't seem to understand how much overkill this is becoming. It's like they're aiming to become 10X USA by 2050 with at least 1 generation ahead in every single military product and technology.
They might consider scaling all this conventional overkill back slightly and focus resources and talent on research and development of completely revolutionary weapons. There's just too much capacity here.
