Russian President Vladimir Putin on Monday declared a three-day ceasefire in the war with Ukraine next month to mark the 80th anniversary of the victory of the Soviet Union and its allies in World War Two.

The Treasury secretary said that the President Trump and Xi Jinping of China have a good relationship but that he was not aware of a call, which Mr. Trump had alluded to last week.

China’s President Xi Jinping has not called President Donald Trump, Beijing said Monday, despite Trump’s claims to the contrary. Trump said in an interview with Time magazine that Xi had already contacted him after Trump triggered a trade war between their countries—the two largest economies in the world—with punishing tariffs.
