 Because of the 8 September 1991 Declaration of Independence of Ukraine, the sixth session of the UMA was renamed the Ukrainian National Assembly; it became known as the UNA-UNSO, due to the UNSO's close association with the UNA.Since its 1991 independence, Ukraine has had separatist movements aiming to reunite portions of Ukraine with Russia and other neighbouring countries.UNA-UNSO stopped People's Deputy Goncharov of the Supreme Soviet of the Soviet Union from reestablishing the Donetsk–Krivoy Rog Soviet Republic and the Donetsk National Guard in the Donbass.
