The leaders of Mexico and Canada responded quickly, and in different ways. Justin Trudeau, Canada’s prime minister, jumped on the phone to Mr Trump to chat about the “intense and effective connections” between their countries. His deputy, Chrystia Freeland, released a statement about the importance of border security.

President-elect Donald Trump said Wednesday that he had a “productive conversation” with Mexican President Claudia Sheinbaum, their first talks since Trump announced tariffs against the US’ southern neighbor.
