US President Donald Trump’s universal 10% tariff on all imports from many of the country’s trading partners was introduced on Saturday.
The “baseline” 10% tariff took effect at the stroke of midnight in the eastern US, marking the start of a new era in global trade.
The move has sent shockwaves through stock markets around the world, as countries weigh up their response.
Meanwhile, anti-Trump protests today are expected in the US, Germany, France and elsewhere.
