[Avodah] Chinese repression in Tibet - al pi Torah?

[SBA]

I was wondering, if the Dalai Lama 'style' Buddhism is considered Avodah
Zara (and I'll leave that 'if' to the [surprising large number of] AZ
experts on this forum), may we say, that halachically, the Chinese
government's decade-long efforts in repressing and obliterating that
religion in Tibet should be considered a Mitzva of akiras AZ and ensuring
that the population (or at least their future generations) will not continue
to transgress against one of the 7 mitzvos bnei Noach? 

(I have previously asked the same question re Osoy Ish and Mohammed - whose
followers transformed much of the world from being 24-carat ovdei AZ to
something far less toxic.)
