 Moscow does not care that Japan is worried about the islands. Medvedev. Moscow is not against signing a peace treaty with Japan, but Tokyo must understand that the Kuril Islands are and will remain part of Russia. Former President Dmitry Medvedev has said, Medvedev, who now serves as deputy chairman of the Security Council, was responding after Japanese Prime Minister Fumio Kishida stated that his country remains firmly committed to the course aimed at resolving the territorial issue and concluding a peace treaty with Moscow despite continuing to support sanctions against Russia over the Ukraine conflict. Moscow and Tokyo have for decades been locked in a territorial dispute over the four Kuril Islands known as the Northern Territories in Japan, which were captured by the Soviet Union at the end of World War II. Russia has argued that its sovereignty over the Kurils is guaranteed by post-war agreements while Japan has said they do not cover some of the islands. Against this backdrop, the two countries ended a formal state of war in the mid-1950s, but never signed a peace treaty. In a post on X, Medvedev stressed that nobody's against the peace treaty, which he said should reflect the fact that the territorial question is closed once and for all in accordance with the Constitution of Russia. The Kuril Islands will be actively developing as their strategic role continues to grow, especially when it comes to the deployment of new weapons in the region, he added, we don't give a damn about the feelings of the Japanese concerning the so-called Northern Territories. Medvedev stated, he suggested that anyone who is unhappy with the situation should end their life in a traditional Japanese way, referring to the seppuku form of ritualistic suicide originating with samurai warriors.
