There has already been a Chinese ship in the Northwest Passage.
Having said that, I don't think this passage is as interesting as the one through the north. China understands that it's more difficult to navigate the Northwest Passage. Anyway, going through the north is more direct. It takes less time to get to Europe, provided you can count on the contribution of Russian icebreakers, which are very active.
A global approach to the Arctic is required. We talk about occupying the territory, but if we aren't there, it's difficult to proclaim our sovereignty and protect territorial integrity. There has to be a physical presence. We have to have planes that fly over the Arctic regularly. We must remember that global warming will make certain resources, such as fish, increasingly available and moving north. We need to be concerned about that, and we need to work with our friends and allies in the Arctic Council.
