Georgia–South Ossetia border

The Georgia–South Ossetia separation line is a de facto boundary set up in aftermath of the 1991–1992 South Ossetia War and Russo-Georgian War, which separates the self-declared Republic of South Ossetia from the territory controlled by the Government of Georgia. South Ossetia, and those states that recognise its independence, view the line as an international border separating two sovereign states, whereas the Georgian government views it as an occupation line in accordance with the Georgian "Law on Occupied Territories of Georgia".
