may 1, 1933 - Japan Leaves the League of Nations
Description:
In September 1932, even before the official announcement of the findings of the Lytton Report on October 2, 1932, was made public, the Japanese government extended official diplomatic recognition to the puppet government of Manchukuo. When the findings of the Report were announced before the General Assembly of the League of Nations, and a motion was raised to condemn Japan as an aggressor in February 1933, the Japanese delegation led by ambassador Yosuke Matsuoka walked out. Japan gave formal notice of its withdrawal from the League of Nations on March 27, 1933. The United States announced the Stimson Doctrine, which warned Japan that areas gained by conquest would not be recognized.
In the end, the Lytton Report basically served to show the weaknesses of the League of Nations and its inability to enforce its decisions. The situation was complicated by the length of time it took for the Lytton Commission to prepare its report, during which time Japan was able to firmly secure its control over Manchuria and was thus able to reject the condemnation of the League with impunity.
