I think 370mm is in close to ~ 300km range.
Self Propelled Gun/Rocket Launcher

I think Shilao's podcast kind of talked about this. They mentioned that 300mm is normally used for targets between 100 to 200 km. 370mm is used for farther away targets. So, I think it's probably reasonable to assume that 300mm can reach range of 220 km (that we've been hearing about) in optimal conditions. And that 350 km is probably the range for 370mm version.
They also talked about the need for PCL191 to have all terrain capabilities, since China can't just build roads to places where they want to launch from.

In fact , do the ranges of rocket artilleries exclusively depend on their diameter ?? Can't increase in length (additional boosters) help in this matter ??
Diameter increase volume too isnt it?
This is a quite complex topic. In general, if we are taking the trajectory as a constant variable to equalize things it mostly depends on burnout velocity and altitude. Burnout velocity is (isp x (ln(fueled mass/final mass)) - (gravity losses + aerodynamic loses). Thus it is about fuel fraction and the propellant. Denser and more efficient propellants are better. Staging helps massively because it allows you to shed empty fuel tanks as you burn fuel saving you from wasting fuel to further accelerate them. Composite bodies, lower payloads, lighter mechanisms and electronics, and ceramic nozzles all help in reducing non-fuel mass. Aerodynamics is of secondary importance since the rocket goes very high but is still important. Increasing the length would increase the ratio of fueled mass/final mass and thus would increase the range. There are limitations to it such as body stiffness and, in larger rockets, thrust-to-weight ratio but is definitely good for range in most cases.

Please stop quoting that fanboy Twitter account.
I wonder if there is a way to block his tweet from being shared on this forum.
