Russian President Vladimir Putin said his five-hour talks with U.S. envoys on ending the war in Ukraine were “necessary” and “useful,” but also “difficult work,” with some of the proposals unacceptable to the Kremlin. Putin spoke to the India Today TV channel ahead of his visit to New Delhi on Thursday, and while the full interview is yet to be broadcast, Russian state news agencies quoted some of Putin's remarks. The Russian leader’s comments come as U.S. President Donald Trump’s special envoy Steve Witkoff and son-in-law Jared Kushner are set to meet with Ukraine’s lead negotiator, Rustem Umerov, on Thursday in Miami for further talks, according to a senior Trump administration official. The high-stakes talks are part of Trump’s renewed push to end the nearly four-year war.
