The Taft–Katsura Agreement was a 1905 discussion between senior leaders of Japan and the United States regarding the positions of the two nations in greater East Asian affairs, especially regarding the status of Korea and Philippines in the aftermath of Japan's victory in the Russo-Japanese War. It was not an "agreement" and did not set out any new policies, but a memorandum. The memorandum was not classified as a secret but no scholar noticed it in the archives until 1924.
