The coat of arms of Viet Nam is modelled after Communist Party symbols, including the yellow star on a red field. The cog and crops represent the cooperation of agriculture and industrial labor in the Communist model. It is similar to the coat of arms of People's Republic of China, and was adopted as the Coat of Arms of the Democratic Republic of Vietnam (North Vietnam) on November 30, 1955. It became national following reunification with South Vietnam on July 2, 1976.
