Two high-ranking members of Russian President Vladimir Putin's inner circle reiterated Putin's June 2024 non-negotiable demands that any resolution of the war in Ukraine must result in regime change, extensive territorial concessions, and long-term limitations on Ukraine's military after US Special Envoy for the Middle East Steve Witkoff's April 11 meeting with Putin. Russian Foreign Intelligence Service (SVR) Head Sergey Naryshkin claimed on April 15 that any future peace agreement ending Russia's invasion of Ukraine must include terms concerning Ukraine's neutrality; the demilitarization and "denazification" of the Ukrainian state; the abolition of Ukrainian laws that allegedly discriminate against Russian-speakers in Ukraine; and the recognition of Russia's illegal annexation of all of Luhansk, Donetsk, Zaporizhia, and Kherson oblasts.[1] Russian Foreign Minister Sergei Lavrov claimed to Russian state business outlet Kommersant on April 14 that the current Ukrainian government is "unconstitutional" and that Russia "cannot give [Russian speakers living in occupied Ukraine] up" following the illegal and sham referendums Russia conducted in the four oblasts to join Russia in Fall 2022.[2] Lavrov reiterated that Putin "very clearly outlined" Russia's demands for a future peace agreement to end the war during Putin's speech on June 14, 2024, and stated that these June 2024 demands were "not some kind of request." Lavrov stated that there are "no secrets" about Russia's demands and reiterated the importance of addressing the "root causes" of the war in a future peace agreement.

Russian officials are using Putin's June 2024 speech as the Kremlin's current standing guidance on negotiations and the resolution of the war in Ukraine. Putin demanded on June 14, 2024 that Ukrainian forces must "completely withdraw" from Ukrainian-controlled territory in Donetsk, Luhansk, Zaporizhia, and Kherson oblasts and that Ukraine must officially abandon its goal of joining NATO (by amending its constitution in which that goal is enshrined) before Russia can agree to a future ceasefire and peace negotiations.[3] Putin stated that Russia is prepared to begin negotiations with Ukraine as soon as Ukraine agrees to withdraw from the entirety of the four oblasts. Putin also demanded that the international community recognize the four illegally annexed and occupied oblasts as part of Russia and lift all Western sanctions against Russia in the event of a resolution to Russia's full-scale invasion of Ukraine. Putin reiterated his calls for Ukraine to agree to full demilitarization and "denazification" and abandon its aspirations to join any external security blocs. These demands would preclude the bilateral security agreements Ukraine has negotiated and is negotiating with several European states.

Putin and other Kremlin officials have routinely issued these same demands, including by using vague language to obfuscate Russia's most extreme demands.[4] Russian officials, including Putin, use this language to articulate their overarching demand that the West acknowledge Russia's illegal annexation of occupied Ukraine and force Ukraine to concede not only territory but also its future sovereignty and ability to defend itself. Kremlin officials have consistently demanded that:

• Ukraine must demilitarize. Putin named "demilitarization" as one of the main goals of Russia's full-scale invasion of Ukraine in February 2022 and stated on July 4, 2024, that Ukraine should undergo "irreversible" "demilitarization" in the event of a future ceasefire.[5] Russia demanded in the April 2022 Istanbul Protocol draft agreement that Ukraine shrink its military beyond pre-2022 levels and commit to never fielding a military capable of defending the country against future Russian aggression.[6] Russia demanded in the protocol that the Ukrainian military should be confined to fewer than 85,000 active-duty personnel, fewer than 15,000 National Guard personnel, and fewer than 1,400 tanks and armored vehicles. The pre-2022 Ukrainian military had 196,600 active-duty personnel, 60,000 National Guard personnel, and over 3,000 tanks and armored vehicles.

• Ukraine must "denazify" and install a "legitimate" government. Putin named "denazification" as another of the main goals of Russia's full-scale invasion of Ukraine in February 2022, and Russian officials have previously defined "denazification" as the "liquidation of those who instill" Russophobia in other people.[7] Russian officials often invoke the term "denazification" to call for regime change in Ukraine and the installation of a pro-Russian proxy government in Kyiv. Putin has routinely labeled all Ukrainian governments since 2014 as "illegitimate" and claimed on January 28 that Russia will not view any agreements it concludes with the current Ukrainian government as binding.[8]

• Ukraine must abandon its aspirations to join NATO or any security bloc in the future. Putin's demand for Ukraine's “neutrality” remains one of the central justifications for his full-scale invasion of Ukraine.[9] Russia demanded in the Istanbul Protocol draft agreement that Ukraine amend its constitution to remove the provision committing Ukraine to NATO membership and add a neutrality provision that would ban Ukraine from joining any military alliances, concluding military agreements, or hosting foreign military personnel or systems in Ukraine.[10]

• Ukraine must concede occupied Ukrainian territory and "Novorossiya" to Russia. Putin stated on June 14, 2024, that Russia will not be content with ending the war on the lines it currently holds and explicitl...
