Russian President Vladimir Putin said Thursday that the United States is taking action to stop the war in Ukraine, in a meeting with Russian top officials ahead of Friday’s summit in Alaska with US President Donald Trump.

MOSCOW (Reuters) -Russian President Vladimir Putin said on Thursday that the U.S. administration was making "sincere efforts" to resolve the conflict in Ukraine and suggested Moscow and Washington could reach a deal on nuclear arms control.

European leaders said a call with President Donald Trump was unifying and that he agreed Ukraine should be part of any negotiations over territory, but some still worry he could give in to Russian President Vladimir Putin.

British Prime Minister Keir Starmer welcomed Ukrainian President Volodymyr Zelenskyy to London, a day before a critical U.S.-Russia summit in Alaska.

The US-Russia summit lets Putin get back to the top table of international diplomacy and thumb his nose at critics. Here’s what else he stands to gain.

With just one day to go until a U.S.-Russian summit on ending the war in Ukraine, its president, Volodymyr Zelenskiy, visited London on Thursday to shore up European support for efforts to prevent any agreement that would carve up Ukrainian land.
