US President Donald Trump has announced increased tariffs on Chinese goods, and the introduction of 25% tariffs on Canadian and Mexican goods from March 4, followed by tariffs on all imported agricultural products starting April 2. The markets reacted negatively, with a fall in US stock indices and prices for corn and soybeans. Canadian Prime Minister Justin Trudeau has stated that if tariffs are imposed on Canadian goods, Canada will impose a 25% tariff on goods from the United States. Economists warn that tariffs could lead to higher prices and inflation in the US, but Trump believes it will ultimately benefit the US economy.
