I have a book written by a French explorer in 1939-40 about Tibet and how the Chinese were gaining influence by putting down bandits and stopping the monks from oppressing the peasants.
I'm not excusing the Chinese but Tibetan Buddhism was pretty horrible and Buddha would doubtless have felt about it the way Jesus would feel about the Orange Order*. The Dalai Lama may be a progressive guy but his predecessors were not.
The Cultural Revolution was an utter disaster for just about everybody in the Chinese sphere of influence and Hong Kong and Taiwan were incredibly lucky to avoid it, but Tibet has a bit more nuance than you might think.
*What is it about the colours orange and yellow and dodgy religions?
