Nations are being forced to choose between siding with China or the U.S. as President Donald Trump’s trade war locks the world’s two largest economies on a collision course.

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 Trump administration has been saying that the two countries are engaged in talks to resolve the dispute, but Beijing asserts that no such discussions are happening.
