Destroying their cultural legacy and killing thousands during the cultural revolution was hardly a beneficial development compared to feudal Tibet modernizing on its own terms.
Lol.
Feudal in the marxist sense.
Tibet had a varied social system across various regions with a caste like system being its main component, such a system is fully capable of modernizing as seen in India and elsewhere on the subcontinent.
Do you actually buy the Chinese propaganda about Tibet being a feudal hellhole with an enslaved population before their glorious socialist "liberation"?
