The Cairo Declaration was the outcome of the Cairo Conference in Cairo, Egypt, on November 27, 1943. President Franklin Roosevelt of the United States, Prime Minister Winston Churchill of the United Kingdom, and Generalissimo Chiang Kai-shek of the Republic of China were present. The declaration developed ideas from the 1941 Atlantic Charter, which was issued by the Allies of World War II to set goals for the post-war order. The Cairo Communiqué was broadcast through radio on December 1, 1943.
The Cairo Declaration is cited in Clause Eight (8) of the Potsdam Declaration, which is referred to by the Japanese Instrument of Surrender.
1943 Cairo Declaration Wikipedia
The several military missions have agreed upon future military operations against Japan. The Three Great Allies expressed their resolve to bring unrelenting pressure against their brutal enemies by sea, land, and air. This pressure is already rising.
The Three Great Allies are fighting this war to restrain and punish the aggression of Japan. They covet no gain for themselves and have no thought of territorial expansion. It is their purpose that Japan shall be stripped of all the islands in the Pacific which she has seized or occupied since the beginning of the first World War in 1914, and that all the territories Japan has stolen from the Chinese, such as Manchuria, Formosa, and The Pescadores, shall be restored to the Republic of China. Japan will also be expelled from all other territories which she has taken by violence and greed. The aforesaid three great powers, mindful of the enslavement of the people of Korea, are determined that in due course Korea shall become free and independent.
With these objects in view the three Allies, in harmony with those of the United Nations at war with Japan, will continue to persevere in the serious and prolonged operations necessary to procure the unconditional surrender of Japan.
