China invaded Tibet? Tibet is a part of China since Tang dynasty! Ur question is like that I ask u if Australian invaded Queensland, very funny!
Tibet is a part of China since 1000 years ago. And Dalai lama is not a monk, he is a politician. The tibet under his governing is far more blooded than communist, it's a slave society. And the land he claims now is a quarter of the whole china which means anywhere if only there is a tibet people lives, it's their land, nope, it's his land. So greedy!
