Canada is slipping behind Mexico as top exporter to the United States. The US Commerce Department released new trade statistics this month that show the US imported $245bn (£194bn) in goods from Mexico in the first 10 months of 2016. The US imported $230bn (£182bn) worth of goods from Canada over that same period. In 2015, Canada and Mexico were tied in exports to the US. The shift in trade comes as President-elect Donald Trump prepares to take office in January. During the US presidential election campaign, Mr Trump said he wanted to renegotiate the 1994 North American Free Trade Agreement (Nafta) between the three countries and threatened to impose tariffs on Mexican-made goods. The real estate mogul said US companies which moved jobs abroad would be charged “a 35% tax when they want to ship their products back into the United States”.Mexico’s jump in the trade relationship with the US is being driven by the automotive industry. The Big Three automakers, Ford, General Motors and Fiat Chrysler, all have a presence there. The manufacturing sector in general, as well as the financial services sector, is also attracting foreign investment.
