After the
Mukden Incident of September 18, 1931, the Japanese
Kwantung Army invaded Manchuria and, by February 1932, it had captured the entire region. The last emperor of the
Qing dynasty,
Puyi, who was living in exile in the foreign
concessions in Tianjin, was convinced by the Japanese to accept the throne of the new Empire of
Manchukuo, which remained under the control of the
Imperial Japanese Army. In January 1933, to secure Manchukuo's southern borders, a joint Japanese and Manchukuo force
invaded Rehe. After conquering that province by March, it drove the remaining Chinese armies in the northeast
beyond the Great Wall into
Hebei Province. From the start of hostilities, China had appealed to its neighbors and the international community but received no effective support. When China called an emergency meeting of the
League of Nations, a committee was established to investigate the affair. The
Lytton Commission's report ultimately condemned Japan's actions but offered no plan for intervention. In response, the Japanese simply withdrew from the League on March 27, 1933. The Japanese army was under explicit instructions from Japanese Emperor
Hirohito, who wanted a quick end to the China conflict and for Japan not to venture beyond the
Great Wall. Japan's negotiating position was very strong, as the
Chinese Nationalists were under severe pressure from the simultaneous full-scale
civil war against the
Chinese communists. ==Negotiations==
