US President Donald Trump delivered one of the first major speeches of his presidency to global business and political leaders at the World Economic Forum in Davos

Trump told the rest of the world that if they do not make their products in the US, they will face tariffs worth "trillions of dollars"

To gasps in the hall, Trump says Canada could "become a state" of the US and that the US did not need Canada's cars or lumber

Trump ha vowed to impose new tariffs on goods entering the US from Canada, Mexico and China on his first day in office, but he has yet to do so
