President Vladimir Putin said on Friday that there was "light at the end of the tunnel" in Russia-U.S. relations and that the two countries were discussing joint projects in the Arctic and Alaska.

Russia’s top diplomat said in an interview released on Friday that “there is no meeting planned” between President Vladimir V. Putin of Russia and President Volodymyr Zelensky of Ukraine, the clearest sign yet that a summit the White House had said was imminent is nowhere close to materializing.

President Trump said in a social media post Monday that he had spoken to Russian President Vladimir Putin and set in motion arrangements for a summit at a location to be decided.
