Just common sense. Russia has vast resource-rich areas in Siberia that with global warming would become habitable. They have relatively few large coastal cities (compared to the US and Europe). And the Arctic sea being clear of ice year round would open up a shorter/faster shipping route for China-Europe than the current one through the Suez canal.

Edit: Also to address your question about whether there are others, I'm Finnish and have strongly considered buying land in Lapland as a long-term investment (thinking grandchildren+ here).
