I see what you mean, but whatever their paranoid reason might be it is time for the Chinese and their interests to let them alone! The more you get to know about Tibetan people and the abuse Chinese did and do over them, the more you see how unfair it is, and the more you get mad. Very little is known in the world about the real situation in Tibet, as it is forbidden to communicate anything about it to the outside world. I have Tibetan friends myself, so I know about it firsthand without the intervention of the news. The situation is harder that most people would ever imagine, it is in fact one of the most brutal genocides that have never existed in our history!
Anyone informed about it, anyone aware about the tortures and horrifying cruelties applied by the Chinese government to the Tibetans would go against this government of horror without even thinking about it, there is no need to investigate anything the situation is as unfair as it can get! They have treated Tibetans worst that they treat animals. And by the way, brutality and cruelty against animals is worst in China that it is in any other place in the world!
I have Chinese friends, so by no means I am generalizing about them. I know by myself that hundreds of millions of Chinese people deeply disagree with their own dictatorship government.
But I also have Tibetan friends, and one of them is called Ven Bagdro. He has written a book about the tortures they did to him for 3 years… but not everything is written, he told me about it personally, while drinking some tea, and I was devastated, could not believe it. The book is called “A Hell on Earth”. He also told me what they did to woman, and it is so harsh, so terrifying, that I would not dare to write it here, it is information that would make you cry like a baby... unbearable, horrendous! That is why it is about time for them to leave Tibet in pease.
All these horrible facts are going to spread like fire, they are growing and growing and growing everywhere through books, web pages, forums, campaigns and so forth. Such a truth is unstoppable and will reach, finally, most people, even if they try hard to stop it.
Here you have a link where Bagdro asks for help:

And for you to see his musical fun and how cool he is, here it is this link, which has an amazing human-rhythm-machine, and Bagdro making some Tibetan rap with it
