US President Donald Trump on Saturday announced sweeping 30 per cent tariffs on imports from the European Union and Mexico, escalating tensions with two of America's most significant trading partners.

The announcement was made through separate letters posted on Trump’s Truth Social account, addressed to Mexican President Claudia Sheinbaum Pardo and European Commission President Ursula von der Leyen.

In his letter to Sheinbaum Pardo, Trump acknowledged Mexico’s assistance in reducing the flow of undocumented migrants and fentanyl across the southern border. However, he insisted that the efforts were insufficient, warning that North America was at risk of becoming a “Narco-Trafficking Playground.”
