On the Antarctic, you're right, there is a comprehensive multilateral treaty governing that continent. But one has to remember that the Arctic is not a continent. The Arctic is largely an ocean. It's a very different situation from Antarctica. The treaty that I referred to in response to your colleague's question, the United Nations Convention on the Law of the Sea, is therefore the dominant governing instrument for the Arctic.
There is a tendency for countries that are not Arctic countries to want in to Arctic diplomacy. They argue for a multilateral global treaty, like the Antarctic treaty, as a way to get in. But Canada, of course, has the longest coastline of any country in the world, most of it in the Arctic. We were lead negotiators on the law of the sea convention. So from a strictly Canadian interest point of view, I would urge you to support the law of the sea convention as much as you possibly can.
There are other multilateral treaties and instruments. The Arctic Council is one organization that is very important in terms of dealing with studies of climate change, for instance. But we do not need to ignore or sideline the law of the sea convention and start again with some new overarching multilateral instrument. First of all, we don't have time. Those things take several decades. More importantly, the instrument in place, the law of the sea convention, is very good indeed.
