1943 Cairo Declaration

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 Three Great Allies expressed their resolve to bring unrelenting pressure against their brutal enemies by sea, land, and air.

[12]On the other hand, then-ROC president Ma Ying-jeou cited a series of instruments beginning with the Cairo Declaration and stated in 2014:[13] The implementation of the legal obligation to return Taiwan and its appertaining islands (including the Diaoyutai Islands) to the ROC was first stipulated in the Cairo Declaration, and later reaffirmed in the Potsdam Proclamation, the Japanese Instrument of Surrender, the San Francisco Peace Treaty, and the Treaty of Peace between the Republic of China and Japan.

The Cairo Declaration is therefore a legally binding instrument with treaty status.Many prominent Koreans in the Korean independence movement, including Kim Ku and Syngman Rhee, were initially delighted by the declaration, but later noticed and became infuriated by the phrase "in due course".

There was significant concern that the trusteeship could be indefinite or last decades, making Korea functionally again a colony under a great power.

[14][15] The phrase "in due course" was not present in the first draft; it originally read "at the earliest possible moment after the downfall of Japan".
