The Chinese Han culture absolutely set out to colonise, conquer and subjugated other areas. Xinjiang, Tibet, Mongolia and Manchuria were all conquered during the Qing dynasty and Zhang He projected power and subjugated city states and cultures during his many naval expeditions out.
Colonisation was common all across all cultures. Look at how the Aztec acted towards their many neighbours.
The reason European colonisation was so “successful” was just a “lucky” fluke of circumstances and technological evolution. Had the same conditions occurred in China first, Europeans would all have been subjugated by them. Not because the many Chinese cultures are worse or better than ours but simply because it’s been an incredibly commonplace activity across all cultures. The European colonisation was just the most “successful”.



Capitalism also occurred in China though, so that cannot be the reason by European colonisation occurred.
