What are the key requirements for successful peace negotiations in the Russia-Ukraine conflict?

Successful peace negotiations in the Russia-Ukraine conflict require transparency and inclusion of all key actors affected by Russian aggression. A European diplomat emphasized it is 'fundamental' that negotiations not take place behind the backs of those most affected, particularly Ukraine and European nations. The United States is advocating for flexibility from both Russia and Ukraine, stating that peace will require concessions from all parties involved. This balanced approach recognizes that ending any conflict demands compromise from every side, while respecting the sovereignty of the nations most impacted by the war's consequences.
