The Russian delegation in Istanbul reportedly framed its demands for a final peace settlement as preconditions that Ukraine must meet before Russia will agree to a ceasefire. Most of Russia’s demands are contrary to US President Donald Trump’s proposed peace plan. Sources familiar with the May 16 Ukrainian–Russian talks in Istanbul reported to Bloomberg that the Russian delegation demanded that Ukraine cede all of Luhansk, Donetsk, Zaporizhia, and Kherson oblasts and Crimea to Russia and that the international community recognize the four oblasts and the peninsula as Russian territory before Russia will agree to a ceasefire.[1] The Russian delegation also reportedly demanded that Ukraine adopt a neutral status, that no foreign troops be allowed on Ukrainian territory, and that Ukraine abandon its demands for war reparations from Russia. Chairperson of the Russian Federation Council’s Committee on Foreign Affairs Grigory Karasin stated on May 17 that the Russian delegation maintained Russian President Vladimir Putin’s June 2024 demands, including that Ukrainian forces withdraw from the entirety of the four oblasts and abandon its NATO aspirations before Russia would agree to a ceasefire and peace negotiations.[2] The United States reportedly presented Russia in April 2025 with a seven-point peace plan that offered Russia “de jure” US recognition of Russian sovereignty over occupied Crimea and “de facto” recognition of Russian control over the parts of Ukraine that Russian forces currently occupy.[3] The US proposal also reportedly included “a robust security guarantee” involving a group of European states and possibly non-European states as a likely peacekeeping force. The Russian delegation’s demands in Istanbul outright reject these aspects of the US peace proposal.
ISW continues to assess that Russia’s war aim remains full Ukrainian capitulation.[4] Russia is reframing its territorial demands — typically the subject of war termination negotiations — as preconditions for a ceasefire.[5] Russia is attempting to posture itself as open to negotiations but is putting forward demands that Ukraine cannot reasonably accept while offering no compromises of its own. ISW continues to assess that Putin will continue to refuse to offer compromises until Ukraine and the West are able to alter his theory of victory, which posits that Russia will win a war of attrition through indefinite creeping advances that prevent Ukraine from conducting successful, operationally significant counteroffensive operations.[6]
