Once you are playing a competent Axis opponent the understand supplies and logistics, China seem doomed to collapse against the Japanese onslaught. Japan has most of the units they need at start or on the production spiral for free. They receive all the units they need for the initial Pacific campaign so you need not divery resources to building naval landing units and such. You will only need to hold back some MMP’s at the correct time to load them up in their transfers. The crush China, there are just a few keys to success:
1 you will only need to buy a few units, such as artillery;
2 you need to research INF-2 and Artillary-1 ASAP; then improve your ground support when practical.
3 Make sure you are keeping your spear point well supplied and in command.
4 Shift the Armies and Corps from Manchuria, replacing them with Garrisons.
You will have no trouble getting positive attrition while steadily increasing your unit experience and destroying key Chinese positions. Once the artillery arrives things get easier; once they are upgraded, it is plain easy.
China can only keep up with the attrition war initially but by 1940 you will knock out some Industrial centers and resources and they will fall way behind. This are pretty desperate for China in 1941 and are sliding fast.
This is very ahistorical. Japan captured Nanning at the end of 1939; but that was about the extent of strategic action for much of the early war. They were repulse three times going after Changsha and did not take it until 1944.
Below is a picture of the last grind down of China (I was China and thought I did pretty well). I am a couple turns from completely shattering.
Some ideas for changes to slow down the Japanese advance.
Create Supply problem: If Japan does not have primary supply and is limited to level 5 supply via ports, this could make the long interior advances more difficult. An HQ on a city would throw level 8 supply. This will be quickly reduced in the mountains.
Create a Partisan problem: Add a lot more partisans behind the initial starting boundaries. If they need to garrision every hex on their supply line, this would make long interior attacks more challenging.
Add economic aid from USSR: The initial 200 in helpful but does not continue. Have a “convoy” option of 50 mmp a turn from USSR to flow through some of their lend lease might create an interesting dilemma for the Allies. Both are in desperate need of MMP’s. Who gets them?
Create a 3 hex US mobilization buffer around Kweichow: The US mobilization barrier seems to help in the north but Japan has a free hand to undercut China in the South. I think this might give a place to retreat and regroup in 1940 after Japan overruns Changsha.
Add US entry impact for Changsha and Chengchow: The loss of there is very impactful on China. US mobilization for these may help offset or delay how soon Japan wants to take these.
