tariffs

Trump hopes the tariffs will boost US steel and aluminium production but critics say it will raise prices for US consumers and dent economic growth.

And there is still the prospect of more tariffs - on Canada and other US trading partners - next month.

However, there has been more geopolitical uncertainty this year than last year, including President Trump's introduction of some tariffs.

The market turmoil is being driven partly by concerns about new taxes on imports, called tariffs, which Trump has introduced since he took office.

During their February meeting at the White House, both Trump and Prime Minister Narendra Modi praised each other's leadership, but Trump criticised India's high trade tariffs, calling them a "big problem."
