- "Russia and the EU" are not directly disputing Donbass, though the EU has imposed sanctions on Russia due to the conflict.
- "Ukraine and Poland" are generally allies, with Poland being a strong supporter of Ukraine.
- "Ukraine and Belarus" are not in a direct dispute over Donbass; Belarus has supported Russia's actions against Ukraine.
