Trudeau had a much frostier relationship with Obama's successor, Donald Trump. The Trump administration forced the renegotiation of NAFTA to create the CUSMA (known as USMCA in the US), in which Canada made significant concessions in allowing increased imports of American milk, weakening Canada's dairy supply management system. Trump also implemented tariffs on Canadian steel and aluminum, to which Trudeau retaliated by imposing tariffs on American steel, aluminum and a variety of other American products. At the 2018 G7 summit, Trump called Trudeau "very dishonest and weak" in response to comments that Trudeau had made in a press conference, regarding Trump's tariffs. Trudeau again drew Trump's ire at the 2019 NATO summit when he was seen on video gossiping with his British and Dutch counterparts, Boris Johnson and Mark Rutte, as well as French president Emmanuel Macron, about a press conference that Trump had held earlier that day. Trump responded by calling Trudeau "two-faced" when asked by a reporter about the incident.
