More than 50 old maps and documents that show evidence of Vietnam's sovereignty over Hoang Sa (Paracel) and Truong Sa (Spratly) archipelagoes are on display in an exhibition that opened in the central city of Hue on September 21.

The exhibition shows four atlases issued by the Chinese government in 1908, 1919, and 1933 marking Hainan island as the southernmost tip of Chinese territory in the East Sea .

Many maps drawn by westerners in the 18th and 19th centuries do not include Truong sa and Hoang Sa archipelagoes as part of Chinese territory either.

The organisers collected old documents issued by the country's last Nguyen Dynasty (1802-1945) that confirm Vietnam's sovereignty over the islands to include in the display.

Experts said the exhibition gives scientific proofs and clear evidence on the sovereignty of Vietnam over the archipelagoes.

The exhibition is open until the end of this month at the Hue Museum of Culture, and entrance is free.-VNA
