The maintenance of law and order in the china–vietnam borderlands during the french colonial period (1896–1940)

The item about border between China and Vietnam is not just a contemporary issue. Its building and its story takes its roots in the past and the colonial period played a major role. This article aims to analyse how the French colonial administration tried to keep order on the Tonkin border. First, the structure of the maintenance of law and order along the border is analysed to better understand how these diverse borderlands areas with a harsh climate and a multi-ethnic population resulted in many issues, giving birth to the challenges of law and order on border. Then, dynamics of cross border criminal activities are studied. The authority of these isolated French colonial troops in the borderlands is usually fragile. In front of this situation, the author will question the colonial administrations response against the threat of cross border criminality. Military actions and police operations are mixed and order and law is kept thanks to an auxiliary force made up of local populations, the partisans, that is the real backbone to maintain law and order in the borderlands.
