I think we should understand the nature of this dialogue. As Professor Burton mentioned, and I'll reiterate:
The Chinese Ministry of Foreign Affairs' mandate is to defend China's interests abroad. It has no institutional interest in promoting respect for China's human rights domestically.
Their mandate is not for the protection of human rights through this dialogue. Their mandate is to show we care about human rights, but no one will speak publicly.
The end result is that this becomes a reward to the country, the dictatorship, and the committee of human rights, for crimes against humanity. They use this as a licence to kill, and they continue to escalate.
We have to seriously consider that it's not one-sided. I know Canadians have compassion and kindness, but it's not a one-sided wish. It depends on the bilateral wish. If the other side has no wish to promote human rights, what's the point of continuing these human rights?
