Could I tackle the second question very briefly, Paul?
First, I'd say that there is no solution to climate change without China. They are far and away the largest producer of greenhouse gases. The effects of mercury landing in our north from Chinese coal generation and electricity generating plants is unstoppable without Chinese collaboration and co-operation. We cannot do that on our own, but perhaps with our American and other allies we can reach a consensus internationally with the Chinese to reduce those threats.
Despite the rocky record of COVID-19 originating in China and this failed vaccine, the reality is that 70% of the medical supplies needed to fight COVID in Canada in March and April of last year were arriving from China and 40% of our medical supplies that are necessary to fight COVID are still coming from China. In medical terms, that vast number of doctors is going to be a benefit. My son's hand operates because of Chinese micro-surgery techniques. Medicine should know no boundaries. We need to be open to those collaborations.
Picking carefully, I would say that climate change, environment, health and perhaps some dimensions of culture would be the safe areas where there are good prospects for collaboration once we get beyond the three Ms.
