Hello and welcome to NewsHour from the BBC World Service.
Coming to you live from London, I'm James Kamarasamy.
It is the 1st of February, the day when Donald Trump takes what he calls the most beautiful word in the dictionary,
tariffs, and turns it into action.
You might call it T day.
The White House has said that from today,
the Trump administration is placing tariffs or extra import duties of 25% on all imports from Mexico and Canada,
while Chinese goods entering the United States will face a tax of 10%,
a triple whammy for America's three biggest trading partners.
President Trump has also warned he'll impose tariffs on goods from the European Union.
