An article regarding China's various SPGs of various calibers and types. Also included is an article on the PCP-001.
In my opinion, in terms of rapid deployment capabilities, China is current ahead of most other nations. Both their marine and airborne corps have access to a completed array of fighting vehicles that are not only easily transported, but also are capable of traversing almost any terrain and are fully amphibious. So in any hypothetical situation whereby heavy lift transportation are limited, a Chinese expeditionary force will be better equipped than any potential opponent. Add in the VT-5 light tank and you got yourself a fully equipped force capable of an armored spearhead approach.
Of course, tactics and the competence of the force's commanders will play a big role in determining the outcome but one can never have too many cards to play with.
Russia has yet to apply this concept beyond that of its Nona/Vena self propelled mortar, whereas the 2S1 Gvozdika is a rather dated SPG. The West had only begun to belatedly consider this concept in earnest. Only recently BAE US had introduced a dual 120mm self propelled mortar concept mjolner which is clearly a ripoff of the AMOS but without the autoloading system, yet somehow none of the forumers of that particular website are lambasting the fact that the US had actually managed to make an even worst copy of an existing system.
