(VOV) - A delegation of Australian war veterans will arrive in Vietnam in late July to return wartime objects to their Vietnamese counterparts in Binh Dinh province. The memorabilia was collected by Australian and New Zealand war veterans during their engagement in the US-waged war in Vietnam between 1966 and 1971. Among the objects were 90 letters found on the Binh Dinh battlefield. This is part of a project which was launched by a group of Australian researchers and war veterans in 2010. Phan Nhu Hai, deputy director of Binh Dinh province’s Department of Labour, Invalids and Social Affairs, says the handover of the memorabilia is a noble deed from the Australian veterans as Vietnam is celebrating 66 years of War Invalids and Martyrs Day (July 27).
