An American with Vietnamese origin will hand over 90 old maps published between 1826 and 1980, which contain further evidence of Vietnam ’s sovereignty over Hoang Sa (Paracel) and Truong Sa (Spratly) archipelagoes, to Da Nang 's Institute for Socio-Economic Development (ISED) next month.

The maps are part of a collection belonging to the president of the Institute for Vietnamese Culture and Education (IVCE), Tran Thang. The institute is a non-profit organisation founded in New York in 2000.

ISED vice director Tran Duc Anh Son said the collection of old maps comprises of three kinds of maps: 68 maps showing that China did not have Hoang Sa and Truong Sa archipelagoes; six maps indicating that those islands belonged to Vietnam; five maps of the Southeast Asian region showing that Hoang Sa and Truong Sa archipelagoes are under Vietnam sovereignty.

"The city's Hoang Sa island district has a plan to build an exhibition hall and we would display the map collection there,” Son said, adding that the institute plans to show off the collection in the ‘Sea and Islands Week' to be held in Khanh Hoa province next April.-VNA
