Tanggu Truce

The Tanggu Truce was a 1933 ceasefire between China and Japan that ended fighting in Rehe and established a demilitarized zone south of Japanese-occupied Manchuria.

Demilitarized zone: An area where military forces or activities are restricted by agreement. The truce created a zone separating Chinese forces from Japanese-occupied territory.
Mukden Incident: A 1931 explosion near Mukden, staged by Japanese officers and used to justify the invasion of Manchuria. It triggered the expansion that led to the truce’s unequal terms.
Chiang Kai-shek: A Chinese military and political leader who headed the Nationalist government during the 1930s. His government accepted the truce while prioritizing internal conflict and military consolidation.
Japanese invasion of China: Japan’s widening military invasion of China, beginning in 1937 and continuing through World War II. The truce did not prevent a later, much larger war between the two countries.
Nine-Power Treaty: A 1922 treaty affirming China’s territorial integrity and the Open Door policy among several powers. Its principles contrasted sharply with the territorial reality accepted by the truce.
Great Wall: A system of fortifications built across northern China over successive periods. The truce’s demilitarized boundary followed the Great Wall in part.
Invasion of Manchuria: Japan’s 1931–1932 military seizure of Manchuria from China. The invasion created the occupation the ceasefire effectively left intact.
Puyi: The last emperor of China, installed as head of the Japanese-controlled state of Manchukuo. His rule embodied the political order Japan sought to protect after occupying Manchuria.
Second Sino-Japanese War: The war between China and Japan from 1937 to 1945, later incorporated into World War II. The truce’s temporary calm preceded renewed full-scale conflict.
Sino-Soviet Non-Aggression Pact: A 1937 agreement in which China and the Soviet Union pledged not to attack one another. Unlike the Tanggu ceasefire, this pact addressed relations with a potential external ally.
