Honor the postwar order
Commitments Japan made when it accepted the provisions of the Cairo and Potsdam declarations must be fulfilled
On Dec 1, 1943, China, the United States and Britain jointly issued the Cairo Declaration, which explicitly states "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". Manchuria, Formosa and The Pescadores stand respectively for present-day China's Northeast, Taiwan and the Penghu Islands.
The declaration also demanded Japan be expelled from all other territories it had taken by violence and greed.
