The exhibition entitled “Vietnam’s Hoang Sa, Truong Sa – Historical and Legal Evidence” is part of a public communication campaign to affirm Vietnam’s sovereignty over the two archipelagos.

On display are photos, documents, objects and nearly 100 maps which have been collected by domestic and foreign researchers and scholars so far.

Many photos and documents reflect the process Vietnam exercised and defended its sovereignty over Hoang Sa and Truong Sa since 1930 until China used force to occupy Hoang Sa on January 19, 1974. There are 65 maps testifying Vietnam’s sovereignty over the two archipelagos announced by Vietnam and Western countries from the 17th century to present.

The exhibit aims to help international friends, including Chinese people, gain a deeper understanding of Vietnam’s history and desire to maintain peace and stability in the East Sea and in the region.
