From your post, I feel you are exposed too much to the propagandas made by the follower medias of your government.
Many innocent people are killed by dalai-lama's brutal followers. Many bloody videos on the YouTube are actually NOT taken inside the territory of China. Many were taken in India and Nepal and the Indian and Nepal policemen acted much more violently than Chinese policemen. The following link is an article written by a western journalist who happened to be in Tibet when the unrest took place in Tibet, read it to know the truth.

I don't want to comment on the Chinese government. I am not satisfied with their system and many of their polices too. However, China is a totally different country from yours. It is VERY hard to father the country to make it peace and quiet and people rich and happy in every corner. The country has suffered from too much insults in the last 150 years. Before that time, we have been used to lead the world for thousands of years. Chinese people were losing belief and confidence since 19th century but now we are trying to seek them back. The western system is not fit for China's complex situation which I bet you know little about. If you want to comment China, you need first come here to see it. As an ordinary Chinese citizen, I live a free, happy and peaceful life here in a modernized metropolitan just like many of you, doing what I like and what I'm interested in. We young people don't often care much about politics actually. I've been to Tibet, several hundreds kilometers from where I live, before this unrest of course. Everything there was also peaceful and lovely, until one day mobs destroyed the harmonious community there. They destroyed shops, robbed banks, killed people. Why don't you condemn them? You think they are acting in the correct way? What if they did these in your country? Tibet is territory of China since several hundreds years ago. This doesn't need to be questioned by you. Dalai-lama wants to be the king of the land in a system of mixing politics and religion, which is definitely not a trend in the world today.
As for Taiwan, I appreciate their democracy. Taiwan and Mainland China are both parts of China. My opinion is that two sides should form a union in a way both can accept. I don't think it's a proper way to force Taiwan to be a province of China which it used to be centuries ago.
Chinese nation is a peaceful nation. We like to be friendly and happy with other people together, with no hostility and hatred. However, there is too much hostility and hatred in our world. When China was the strongest in the world, it didn't ever think of invading other countries, while many other countries did this when they became the world strongest. If you fear China will threaten your countries in the future, that's because you are thinking in your logic.
We must accept the fact that we are living a world with diversity. Nobody should force others to behave in the way that he thinks is right.
When things work together, things work.
