I think he made a short-term political calculation to remove a short-term problem of pressure on vulnerable sectors in Canada, particularly canola.
I can understand the imperative to do that, but one needs to then have reversibility and step-back provisions. The problem is that the deal trades several months of restored trade in that sector for what is potentially a permanently embedded relationship. Once you have dealer networks, once you have consumer brand loyalty, if you start to have investment and so on, that becomes hard to reverse.
You need to factor into that Canadian values and the protection of human rights. These are not tradable items. You cannot simply choose between trade and human rights because, ultimately, the human rights situation in China is embedded in the trading relationship.
