Boxer Protocol
The IJA 5th Division was dispatched to protect Japanese nationals and property in Tianjin China in June 1900 after the start of the Boxer Rebellion. It formed the core of the Japanese expeditionary forces in northern China. Under the terms of the Boxer Protocol, Japan was allowed to maintain a military garrison to guard its embassy, concessions in China, as well as certain strategic fortifications and ports. The IJA 5th Division was thus transformed into the Chinese Empire Garrison Army in June 1901.
