The numbers given in the OP were about empire, extending and maintaining imperial domination domination over lands and people not yet or only partly conquered and controlled Of course, facts rarely matter to people with your viewpoint, but on the off chance you might be interested....
The Civil War in China was between CPC and the KMT. Claiming that only Mao was responsible for the deaths is just silly. One can as easily and ridiculously argue that only the KMT was.
Or for that matter, it makes even more sense to add these deaths to the US's planet-wide mass murdering in the OP, since the US role in arming and supplying the KMT prolonged the conflict for years while the deaths continued to mount.
With the breakdown of talks, an all out war resumed. This stage is referred to in Communist media and historiography as the "War of Liberation" (simplified Chinese: 解放战争; pinyin: Jiěfàng Zhànzhēng). The United States assisted the KMT with hundreds of millions of dollars worth of new surplus military supplies and generous loans of hundreds of millions of dollars worth of military equipment.<36> They airlifted many KMT troops from central China to the Northeast (Manchuria). President Truman was very clear about what he described as "using the Japanese to hold off the Communists". In his memoirs he writes "It was perfectly clear to us that if we told the Japanese to lay down their arms immediately and march to the seaboard, the entire country would be taken over by the Communists. We therefore had to take the unusual step of using the enemy as a garrison until we could airlift Chinese National troops to South China and send Marines to guard the seaports".<37> Over 50,000 Marines were sent to guard strategic sites.

According to the Battle Summary in the 4 Years' Liberation War, from July 1946 to June 1950, the PLA eliminated 8,071,350 KMT forces and bandits, among them over 6,360,000 surrendered/defected/captured. Another calculation put the total enemy eliminated to about 10,658,000, which is based on combined unit reports. The PLA suffered more than 260,000 KIA and 1,040,000 WIA
