My only comment is that my understanding, as indicated earlier, is that there is a draft text of the agreement on Arctic Ocean oil pollution preparedness and response. So if it is not prepared, adopted, or whatever, I suspect without knowing so that this will be on Canada's Arctic Council agenda. There may be other things that I'm just not aware of which will be Arctic-specific.
But I would say that there is certainly room for Arctic-specific treaties, much as there are specific treaties that deal with the Mediterranean, the North Sea, the South China Sea. There are specific agreements that are regional in orientation; there's no reason that this model can't apply to the Arctic.
