America’s deal with Mexico will make NAFTA worse

TRADE disputes have scarred the presidency of Donald Trump. So markets rose in relief when America and Mexico announced on August 27th that they had agreed on changes to the North American Free Trade Agreement (NAFTA). Mr Trump had earlier threatened to walk away from the deal, which eliminated most tariffs between its signatories after coming into force in 1994. As The Economist went to press, it was not clear whether Canada, the third party to NAFTA, would join the deal (see article). But across one border, at least, the threat of a trade crisis looks a bit less likely.
