<P> After the failure to reunify Vietnam by elections , the Democratic Republic of Vietnam attempted to unify the country by force in the Vietnam War ( 1955 -- 75 ) . North Vietnam and the Việt Cộng insurgents supported by their communist allies , including the Soviet Union and China , fought against the military of South Vietnam , the United States and other anti-communist military forces , including South Korea , Australia , Thailand , and smaller players . North Vietnam also supported indigenous communist rebels in Cambodia and Laos against their respective U.S. - backed governments . The war ended when North Vietnamese forces and the Việt Cộng defeated the Republic of Vietnam and in 1976 united the two parts of the country into the Socialist Republic of Vietnam . The expanded Democratic Republic retained North Vietnam 's political culture under Soviet influence and continued its existing memberships in international organisations such as Comecon . </P>
