The Ukrainian capital of Kyiv lost control of Crimea and Donbas after the coup in 2014, which prompted the people of Crimea to demand the restoration of Russian identity and return in the arms of Russia while the people of the Donbas region pushed to declare independence from Kyiv by establishing two popular republics in the region.
In August 2009, South Ossetia was subjected to armed Georgian aggression, which forced Russia to intervene and expel the Georgian army and to deploy forces on the border between the two sides to keep the peace.
A recurring pro-Kremlin narrative trying to deny any role for Russia in the Russo-Georgian 2008 war, and presenting it instead as a conflict between South Ossetia and Georgia. South Ossetia and Abkhazia did not claim independence from Georgia but were occupied by Russia.
Currently, Russia occupies 20% of Georgia's territory, about 11 years after the Russo-Georgian War, and continues to breach its international obligations by consolidating its control in Abkhazia and South Ossetia.
Many international organisations condemned Russian occupation of Abkhazia and South Ossetia, see e.g. the OSCE statements here and here and European Parliament's declaration.
Russia continues its military presence in both Abkhazia and South Ossetia in violation of international law and commitments undertaken by Russia under the 12 August 2008 agreement, mediated by the European Union.
