What is the official currency of Vietnam?
The đồng has been the currency of Vietnam since May 3, 1978. Issued by the State Bank of Vietnam, it is represented by the symbol "₫". Formerly, it was subdivided into 10 hào, which was further subdivided into 10 xu, neither of which is now used.
The word đồng is from the term đồng tiền ("money"), a cognate of the Chinese tóng qián (Traditional Chinese: 銅錢; Simplified Chinese: 铜钱). The term refers to Chinese bronze coins used as currency during the dynastic periods of China and Vietnam. The term hào is a cognate of the Chinese háo (Chinese: 毫), meaning a tenth of a currency unit.
