U.S. President Trump has announced a doubling of tariffs on steel and aluminum imports from 25 percent to 50 percent, effective June 4, sparking a global backlash, particularly from key U.S. trading partners like Canada and the European Union (EU).

Canada, the largest supplier of steel and aluminum to the U.S., has warned that the move will severely disrupt its industries, affecting half of its production. The EU, another major trading partner, condemned the decision, stating that it undermines ongoing trade talks and risks further escalating tensions.
