Nearly 100 maps and several publications written by Vietnamese and foreign historians and researchers are on display. They include transcribed versions of the original Chinese-Vietnamese and French documents published by Vietnamese feudal regimes and the French government in Indochina from the 17^th to the 20^th century.
The documents confirmed Vietnam’s sovereignty and activities to protect its sovereignty over the Truong Sa and Hoang Sa archipelagos such as the Hoang Sa marine war on January 19^th, 1974. Old Chinese maps and atlas at the exhibition show that China had not managed Hoang Sa and Truong Sa archipelagos. The exhibition will open until December 19.
