Car accident rates are higher in China, you are also more likely to die because of pollution. People are not very unified, which is why the government focuses more on internal security than external security. The PLA has killed way more Chinese in the last 30 years than foreign combatants.
Well, considering the PLAs only major combat action in the last 30 years has been in Beijing, they probably aren’t eager to publicize that. Thought I have a hunch that it is true for the PLAs entire existence (they never killed many Japanese, and the Siege of Changchun claimed at least 500k compared to anything that happened in Korea).
I'm sure the PLA keeps and makes available to all & sundry its detailed internal records of who got liquidated and why; and is always open to the scrutiny and criticism of concerned third-parties.
I mean, if you can't expect that kind of service from the military wing of an unaccountable authoritarian maoist kleptocracy...why even have one??
I don't think the PLA gets called in for executions when the PAP can do the job just as well. So the PLA's internal deployments are more likely to be something like fighting separatist groups, which they might want to boast about.
