Donald Trump has warned of increasing tariffs on European Union goods if they impose retaliatory tariffs on US products, intensifying a global trade conflict. Canada has declared 25 percent retaliatory tariffs on US steel and aluminum goods, affecting items valued at a total of US$20 billion. According to a Reuters/Ipsos poll, 57 percent of Americans view Trump's tariff measures as unpredictable, with 70 percent anticipating price increases due to tariffs. Trump emphasized a tough stance on tariffs by stating, 'Whatever they charge us, we're charging them,' as trade tensions rise with Canada and the EU.
