Nothing about Ukraine without Ukraine
"Nothing about Ukraine without Ukraine" is a foreign policy principle that became relevant during the Russian–Ukrainian War, especially after Russia's full-scale invasion of Ukraine on February 24, 2022. The expanded meaning of the phrase is that there can be no negotiations (for example, on a ceasefire during the Russian–Ukrainian war) without the participation of Ukraine at the negotiating table.
This statement is a special case of the formula "Nothing about us without us", known since the 16th century in Central Europe, when the Kingdom of Poland adopted the "Nihil novi" Law, which prohibited kings from passing new laws without the consent of the nobility.
