Tibet is a part of China ??? Do you really believe what you are saying ? Like I have alright said, Tibet has its own culture, his own language, his own history... The Tibet's history... I believe you never learned it to school.. I also never learned it but I know today Tibet has been a great empire during a long time with a great territory, bigger than the actual Tibet. I realize my knowledges are poor, but I'll found back the article which explained Tibet's history in few time... Anyway, you can't assure Tibet is a part of China !!! But, indeed, it's going to become one because of the "progress" you are giving to him. Airports, stations, railway, high ways.... All these things will help the Han people to colonize the Tibet. In Lhassa, less and less people are Tibetans !!! The Han people find work with all these great public works !! They are settling in Tibet, more and more... It's an invasion... Because, after the riots during 2008, you government understood the importance to control this region.
Moreover, if Tibet is today """ a part of China """, it's because all the great asian rivers come from it !!! Just look a map ! But I've alright say that and I don't want to repeat myself. There is also the reason of the ore... For the rivers, I'm looking my world map : indus, mékong, gange, brahmapoutre, salouen, yang-tse-kiang, machu, ... And, please, remember that the water is a great problem in China...
