I see that I only have about a minute and a half left, so I do want to jump to the co-operate C, if you like.
On the question of climate change, to what extent does Canada co-operate in any way with China to counter issues of CO2 emissions and climate change more generally? I ask that question simply because I think it's a topic of concern, obviously, when it comes to emissions. The emissions of China are serious indeed, and finding ways to co-operate with regimes, even when we have strong differences, is an important thing.
