US President Donald Trump's sweeping new tariffs on countries around the world have come into effect in an escalation of his trade war. "IT'S MIDNIGHT!!! BILLIONS OF DOLLARS IN TARIFFS ARE NOW FLOWING INTO THE UNITED STATES OF AMERICA!" he said on social media minutes before midnight in Washington, DC.

The Trump administration implements sweeping tariffs while securing deals with key partners and maintaining temporary truces with Mexico and China.

Brazil has requested consultations at the World Trade Organization over tariffs imposed by U.S. President Donald Trump on the South American nation.
