Nearly 150 photos and 100 documentary materials, old bibliographies and atlases displayed at the exhibition show that the state of Vietnam, over periods, had established, enforced and protected the national sovereignty over the two archipelagoes of Hoang Sa and Truong Sa and other islands and territorial waters belonging to Vietnam’s territory.

It is an enduring and prolonged process, which has been recorded in many historical sources of Vietnam and other countries around the world.

The exhibition has attracted a large number of youth, students, armed forces and people in coastal communes. It will last until October 7th./.
