An exhibition of historical evidence proving Vietnam’s sovereignty over Hoang Sa (Paracel) and Truong Sa (Spratly) archipelagos opened in Vo Nhai district, the northern province of Thai Nguyen on August 5.

On display are 600 documents, books, newspapers, photos, posters, and maps, all declaring Vietnam’s sovereignty over the two archipelagos.

The exhibits underlined the especially important role of sea and islands in the country’s socio-economic development, and national security and defence.

Documentary films on national seas, islands and borders are being screened during the five-day event, which aims to help promote patriotism, solidarity and sense of responsibility among people from all walks of life in protecting sea and island sovereignty.-VNA
