The Weihsien Internment Camp was a Japanese operated Civilian Assembly Center in the former Wei County , located in the present-day city of Weifang, Shandong, China. The compound was a Japanese-run internment camp created during World War II to keep civilians of Allied countries living in Northern China. The camp's population included British, Canadian, American, Australian and other citizens who were forced to stay in the camp for nearly two and a half years until American forces liberated them on August 17, 1945. Information on Weihsien has been learned through papers, diaries, official reports and letters written by internees, family members, and other people affected.
