Russian President Vladimir Putin rejected Ukrainian President Volodymyr Zelensky's invitation to engage in bilateral negotiations in Istanbul and continues refusing to offer concessions to end the war in Ukraine. Putin spoke to media organizations on the night of May 10 to 11, following the May 10 joint US-Ukrainian-European proposal for a general ceasefire for at least 30 days beginning on May 12. Putin did not agree to the joint US-Ukrainian-European proposal and instead proposed that Russia and Ukraine "resume" on May 15 the direct negotiations that he claimed Ukraine "interrupted" in 2022 in Istanbul.
