The total size of the CCP Army, including the New Fourth Army, which was newly formed in November 1937, did not exceed 70,000 people. Its power was weakened further by internal fractional politics; it could have been eliminated in a single battle.  If the CCP were to face the Japanese in battle, it would not be able to defeat a single division of Japanese troops. Sustaining its own power rather than ensuring the survival of the nation was the central focus and the reason for its emphasis on “national unity.”

After the Japanese occupied the city of Shenyang on Sept. 18, 1931, thereby extending Japanese control over large areas in northeastern China, the CCP fought alongside Japanese invaders to defeat the KMT.

The Japanese set up a covert biological and chemical warfare research and development unit in [[Harbin]]. Unit 731 and its affiliated units  were involved in research, development and experimental deployment of epidemic-creating biowarfare weapons in assaults against the Chinese populace (both military and civilian) throughout World War II. Plague-infected fleas, bred in the laboratories of Unit 731 and Unit 1644, were spread by low-flying airplanes upon Chinese cities, including coastal Ningbo and Changde, [[Hunan]] Province, in 1940 and 1941.<ref name="ciadoc" /> This military aerial spraying killed tens of thousands of people with [[bubonic plague]] epidemics. An expedition to [[Nanjing|Nanking]] involved spreading [[Typhoid fever|typhoid]] and paratyphoid germs into the wells, marshes, and houses of the city, as well as infusing them into snacks to be distributed among the locals. Epidemics broke out shortly after, to the elation of many researchers, where it was concluded that paratyphoid fever was "the most effective" of the pathogens.<ref>{{Cite web|url=http://the-eye.eu/public/concen.org/Sheldon%20H.%20Harris%20-%20Factories%20of%20Death%20-%20Japanese%20Biological%20Warfare%2C%201932-1945%2C%20and%20the%20American%20Cover-Up%20%28pdf%29%20-%20roflcopter2110%20%5BWWRG%5D/Sheldon%20H.%20Harris%20-%20Factories%20of%20Death%20-%20Japanese%20Biological%20Warfare%20%28pdf%29%20-%20roflcopter2110%20%5BWWRG%5D.pdf|title=Factories of Death |last=Harris|first=Sheldon|page=77}}</ref><ref>Barenblatt, Daniel.
