Russian-occupied territories

Since the dissolution of the Soviet Union in 1991, Russia has been involved in territorial disputes with a number of other post-Soviet states. These disputes are primarily an aspect of the post-Soviet conflicts, and have led to some countries losing parts of their sovereign territory to what a large portion of the international community designates as a Russian military occupation. As such, these lands are commonly described as Russian-occupied territories, regardless of what their status is in Russian law. The term is applied to Georgia (in Abkhazia and South Ossetia), Moldova (in Transnistria), Ukraine (in Crimea, Donetsk, Luhansk, Kherson, and Zaporizhzhia) and sometimes Chechnya (completely occupied).

Additionally, Russia and Japan have been involved in the Kuril Islands dispute due to Russia's 1991 inheritance of control over the four southernmost Kuril Islands, which Japan has claimed ownership of since 1945.
