President Donald Trump will implement tariffs Saturday on the three largest US trading partners — Canada, Mexico and China — saying there was nothing they could do to forestall him while vowing further levies on various industries.

Canada, China, and Mexico are the United States' three largest trading partners. In 2023, the last full year for which data are available, the U.S. imported $475 billion of goods from Mexico, $426 billion from China, and $418 billion from Canada.

Mexico and Canada are Wisconsin’s two largest trading partners, supporting a combined $25 billion in cross-border trade in 2023.
