I'll just add to the comprehensive answer by Jon Quinn.
Obviously, the co-operation between Russia and China remains a high interest item here in the command. We are also monitoring the current Ukraine crisis conflict in terms of potential co-operation moving forward between Russia and China, given the isolation of Russia following their invasion of Ukraine. We understand that there is co-operation at the economic level in the exploitation of resources, and we're tracking that. So that's an element of interest.
As Mr. Quinn pointed out, Russia has a high interest in the Arctic, given that it derives a fairly significant amount of its GDP in the region and therefore sees the region as a potential national security interest item. They have generated an investment in their infrastructure in the north over the last five years that we've been able to witness. It's an element that we monitor closely.
