They are definitely a tool of propaganda. I don't know how much the ambassador was briefed about the situation inside Tibet before his visit, but I think you need a lot more briefing. These are all tours conducted by the government, which wants the ambassadors and visitors to see only those places, institutions and people that it wants them to see. It does not reflect the reality of the situation inside Tibet.
If Tibet has been turned into a socialist paradise, as they claim, why can't they allow not just ambassadors but also people from all walks of life to come into China? I would urge the Canadian Parliament to move an act similar to the United States'. Reciprocity is the foundation of diplomatic relations, and reciprocal access to Tibet or Uighur is very important, because any Chinese person can come to any part of Canada.
There's no restriction for any Chinese person to visit any part of Canada. However, if a Canadian goes to China, you need another permit to go into Tibet. There is no reciprocity in that. If the Chinese are not afraid of showing the socialist paradise they have turned Tibet into, why don't they allow people to come in and see it for themselves? Why is it only select people, like ambassadors, who are taken to selected parts of the institutions and areas they want them to see?
I am sure the ambassador may not have been.... Of course, we are not denying that there is development in Tibet. There is development, but again, the development is for whom? That is a big question.
