President Trump talked about the tariffs he imposed on Canadian, Chinese and Mexican imports during a gaggle with reporters, and accused China of "running the Panama Canal."

The Trump administration is imposing tariffs through its new International Emergency Economic Powers Act that will range from 10% to 25%.

On Saturday, Trump signed an order imposing substantial tariffs on imports from Canada, Mexico, and China. In response, China’s commerce ministry announced it would file a complaint with the World Trade Organization and “take corresponding countermeasures,” though details were not provided.
