(VOVworld) – Numerous artifacts found in late 2013 and early 2014 have contributed to Vietnam’s archeological achievements while encouraging for appropriate preservation plans. Delegates agreed to this at the closing ceremony of the 49^th conference of the Vietnam’s Archaeological Institute on Friday in Hanoi.

Most noteworthy among the artifacts were items recently excavated off the Truong Sa, Nam Yet, Phan Vinh and Son Ca islands in central coastal Khanh Hoa province. Deputy Head of the Vietnam Institute of Archaeology, Bui Van Liem, said: "The results are clearly scientific proof of maritime activities of prehistoric inhabitants, as well as Vietnamese people, in the country's early history. These materials contribute to affirming vividly and strongly the territorial sovereignty of the country over the land and waters of Vietnam."
