I do. Now, I'm not an expert on this. My colleague Dr. Charron, who has been here, is the real expert on this, but I would suggest there are two things here.
If the Chinese motive to engage in the Arctic is a function of their economic interest to be able to move goods more efficiently and cost-effectively to Europe and the eastern seaboard of the United States, then, from what I understand, it is a function of currents and the way the earth rotates and where the ice breaks out. The ice always ends up clogging parts of the passage. As a result, it's the eastern passage, the Russian passage, that is the much easier and more profitable one.
In my view, China's emphasis on the Northwest Passage is really not economic, but China saying, “We are a great power. We have global interests. Whenever there are global questions”—and they include the Arctic—“we have to be included.” This is a message to Canada along those lines.
