European leaders on Thursday emphasized that Ukraine and European countries must be consulted on any efforts to end Russia’s invasion, amid reports of a proposed U.S.-Russia peace plan that could require major concessions from Kyiv.

The plan, first reported by Axios, reportedly includes granting Russia control over parts of eastern Ukraine, rolling back some U.S. military assistance, and other territorial concessions. Ukrainian President Volodymyr Zelenskyy has repeatedly rejected ceding territory.

EU foreign policy chief Kaja Kallas said, “For any plan to work, it needs Ukrainians and Europeans on board.” German Foreign Minister Johann Wadephul echoed the stance, stressing that all ceasefire and peace negotiations must involve Ukraine and Europe.

U.S. officials, including Army Secretary Dan Driscoll, visited Kyiv Thursday to advance diplomatic efforts, while White House deputy chief of staff Stephen Miller highlighted President Trump’s goal to achieve peace in Europe. Kremlin spokesman Dmitry Peskov said no formal consultations with the U.S. are currently underway.

European diplomats have expressed concern over being excluded from peace talks and criticized Russia for continuing attacks on civilian infrastructure. Kallas condemned the recent strike on Ternopil that killed 26 people, saying Moscow could have agreed to an unconditional ceasefire earlier.

Polish Foreign Minister Radosław Sikorski underscored Europe’s role, stating that as the main supporter of Ukraine, it expects to be fully consulted on any peace efforts.
