Peace efforts between Russia and Ukraine took a cautious step forward as Russian delegates arrived in Istanbul on 15 May for proposed negotiations. Volodymyr Zelensky had invited Vladimir Putin to meet in person, but Putin declined, appointing aide Vladimir Medinsky to lead Russia’s delegation. The absence of top Russian officials, including foreign minister Sergey Lavrov, cast doubt on Moscow’s seriousness. Ukraine, emphasising the need for high-level talks, questioned the format and substance of the meeting. Zelensky said he would decide Ukraine’s response after seeing Russia’s true intentions. Ukraine and its allies had urged an unconditional ceasefire from 12 May, a proposal Moscow ignored. Donald Trump, who at one stage expressed interest in attending, will not participate, though Marco Rubio, Steve Witkoff, and NATO secretary Mark Rutte could do so. The situation remains fluid, with uncertainty surrounding whether the talks will lead to meaningful de-escalation or remain another missed opportunity.
