I think that the Bhuddist Monks have done the most effective thing they could to oppose their repressive government-passive resistance.
Unfortunately the people in power don't give a damn how much passive or even active resistance they face , they have the power to carry on regardless and they have the backers that will help them do it .
It is not in Chinas interest to mess up their beneficial relationship with the junta and there is no movement within China abe to oppose their leaders policies .
Ghandi had success with his movement because Britain was getting massively diminishing returns from India , its power and influence were in serious decline , there was a healthy opposition in government and the people had a voice .
Since it is not in other countries interest to put sufficient pressure on China to force them to change policy they are not going to do it .
