All nice, except that it's not based on actual historical evidence. No great power became great by minding their own business and never coveting their neighbors land. China would not be as big today if it was not for centuries(actually millennia) of successful conquests. The latest to be thanked to Qing, the very Confucianist who were denounced by CCP. Nor would the US, nor would Russia, etc. Having said that, I think that attempts to predict the foreign policy of a modern industrial nation today based on how it's pre-industrialized precursor behaved several centuries ago are flawed and useless.
This is a good read:
I read your link It is nothing but mish mash of half truth and innuendo couple with ignorance
China got so big because combination of chasing the invaders on the north side of the border and slow infiltration to the south
Take example of Xinjiang and the Tarim basin. during the Han dynasty the Xiong nu often raid and invaded China To secure the border the Wu emperror of Han dynasty launch an expedition to the north west and Chased the Xiong nu all the way to the west and that is how China got hols of the west They uyghur and the kazakh are recent immigrant Their original homeland is in inner mongolia . After the destruction of their Kingdom by the Dzunghar they were given land in Xinjiang to live in the 8th century. So Xinjiang has always been in Chinese possession since 1st Century BC. But due to the distance , logistic and flow and ebb of Chinese dynasty they cannot maintained constant control over the area . Only when China is strong she will reestablish control and due to war with Dzungar who was the original inhabitant of Xinjiang the Qing once and for all incorporate it as Chinese territory. So to say that China invade and conquer Xinjiang is not correct.
Yes they are not Han but ethnicity and nationality are 2 different thing and people often confused it resulting in tragedy. The present harsh crackdown on the Uyghur is because they started first by rioting and killing hundreds of Han people But western press never mention it They just paint China as Nazis bent on genocide. China didn't treat the Hui or the Tajik harshly.
In the south China gain the territory over hundred of years thru immigration and inter marry with the local inhabitant who is more than willing to accept Chinese culture and civilization Thru the many war and natural disaster million of Chinese migrated to the south Most of them are soldier from the defeated faction or refugee from natural disaster There they intermingle and intermarry with the Kadai, Yue, She and other Austornesian people.
So over hundred of years they become Han Chinese and think themselves as Han Chinese
The current Chinese name "Xinjiang", which literally means "New Frontier" or "New Borderland", was given during the

's report to the Emperor of Qing, Xinjiang means an
"old land newly returned" (故土新歸), or the new old land. (Note that "returned" [gui 歸] here is an ideological term, which does not indicate a "return", but what ought to be, from the Chinese empire's point of view).

Meanwhile, after the Uyghur Khaganate in Mongolia had been smashed by the Kirghiz in 840, branches of the established themselves in (Karakhoja) and , near the modern cities of Turfan and Urumchi. This Uyghur state remained in eastern Xinjiang until the 13th century, though it was subject to foreign overlords during that time. The Kara-Khanids converted to Islam. The Uyghur state in eastern Xinjiang remained , but later converted to .
The Qing dynasty of China gained control over eastern Xinjiang as a result of a that began in the 17th century. In 1755, with the help of the Oirat noble , the Qing attacked and captured the Dzungar khan. After Amursana's request to be declared Dzungar khan went unanswered, he led a revolt against the Qing. Over the next two years, Qing armies destroyed the remnants of the Dzungar Khanate and many Han Chinese and () moved into the pacified areas.
