ITHACA, NEW YORK – US President Donald Trump’s return to the White House has been accompanied by dramatic economic-policy shifts, setting countries around the world on edge. The new administration has imposed sweeping tariffs on Chinese, Mexican, and Canadian imports – pausing, reinstating, and later granting temporary exemptions for goods compliant with the US-Mexico-Canada Agreement (USMCA). In response, both Canada and Mexico have announced retaliatory tariffs on key US industries, while Trump has vowed to impose “reciprocal” tariffs on “everybody across the board.”
