I would say, very quickly, that Russia doesn't get to choose the parts of the rules-based order it wants to participate in. They have eliminated themselves at the moment from discussions, because they have not proven themselves to be a trustworthy member of the rules-based order. They need to come to the table and account for what they've done in Ukraine.
That said, many multilateral fora go on. The Arctic Council is under discussion. It is moving to Norway in terms of the chairmanship.
A really critical element in terms of safety in the Arctic is the Arctic Coast Guard Forum. It was begun in, I would say, about 2015, and it's where Arctic coast guards talk about ecology, policing, safety and search and rescue.
