Earlier Denmark announced its desire for the pole. Russia recently released a geological study claiming the ridge was part of the Asian continental shelf and therefore Russian.
Much like Danish-Canadian fights over the Arctic, this may seem pointless but never underestimate the desire to control territory and resources. This fight may also have a major affect on international travel. Flights from the Far East to the United States take the great circle route over and near the North Pole because of the international access. An aggressive Russia may one day cut off this path thus making it much more difficult and costly to send people and material across the world.
