The event is part of a series of activities to raise public awareness about Vietnamese sovereignty and the national border, said Hoang Ngoc Son, Director of the Cao Bang Department of Information and Communication.
In addition to over 300 maps, documents and photos about Vietnam’s sovereignty over the Hoang Sa and Truong Sa Islands, the exhibition also displays photos of the ASEAN community and the ethnic groups in Vietnam.
The exhibition will run until July 10.
