(VOVworld) – Precious documents including hundred-year-old maps on Truong Sa (Spratly) and Hoang Sa (Paracel) archipelagos have been displayed in the central province of Ha Tinh. The week-long exhibition drew a huge number of both domestic and foreign visitors and received 1,000 testimonials. The materials are evidence of Vietnam’s indisputable sovereignty over the two archipelagos.
