The Washington-based think tank Center for Strategic and International Studies said in a September report that, overshadowed by the invasion of Ukraine, Moscow's militarization of the Kuril Islands "has flown largely under the radar." "Russia's steps to boost its presence suggest that the islands will continue to play a pernicious role in the future of Russo-Japanese relations and that Japan and the United States should deepen consultations regarding Russia's activities in the region," according to the report, published on the centre's website.
