Japan–Taiwan relations "The terms of the Cairo Declaration shall be carried out and Japanese sovereignty shall be limited to the islands of Honshū, Hokkaidō, Kyūshū, Shikoku and such minor islands as we determine." Statements and principles set in the Joint Communiqué of 1972 were written in the Treaty of Peace and Friendship between Japan and the People's Republic of China in 1978. Japan and the PRC agreed to continue abiding by the treaty when former Prime Minister of Japan Shinzo Abe visited Beijing on 8 October 2006. In 1998, Japan and the PRC signed the Japan–China Joint Declaration on Building a Partnership
Japan–Russia relations leaders decided to sign off on joint projects in five areas — aquaculture, greenhouse farming, tourism, wind power and waste reduction. At the 2018 Thirteenth East Asia Summit in Singapore, Shinzo Abe followed up on a proposal from Vladimir Putin to sign a peace treaty without preconditions by the end of the year. He said that the leaders would seek a peace treaty to the terms of the 1956 Soviet–Japanese Joint Declaration. The declaration gave Japan the Habomai islet group and Shikotan while the Soviet Union claimed the remaining islands, but the United States did not allow the 1956 treaty.
