Combat zone
Battle of Khasan (July, 1938-Augast, 1938)
Battle of Khasan was a military clash on the border near Lake Khasan.
Kwantung Army ignored the meandering of the river and insisted on a straight border, but in reality the border was drawn along the river. This area had long been a demilitarized zone, but the battle began after the Soviet troops built a position in July 1938.
Early battle of Khalkhin Gol (May 11-29, 1939)
Battle of Khalkhin Gol was a border conflict between Mongolia and Manchuria.
In 1937, Manchukuo learned from the research of Japanese historians that the borders claimed by the Soviet were correct, but Kwantung Army ignored them. The clash that began on May 11 escalated and continued until both sides withdrew on the 29.
Battle of Khalkhin Gol (July, 1939-Augast, 1939)
Japanese offensive failed and suffered catastrophic damage because it used only 1.5 division and a tank unit.
