President Donald Trump signed executive actions on Wednesday imposing a 50% tariff on Brazil, a 50% tariff on certain copper products and suspending a tax perk for all countries that allowed cheap packages to fly into the US duty-free.

Now, as the 90-day pause on those and other targeted US tariffs is set to expire, Trump has raised Brazil's rate to a whopping 50% – potentially launching a trade war with Latin America's biggest economy, which sells large amounts of beef, coffee, steel and other products to the United States.
