US goods face new tariffs as Canada, Mexico, China respond to Trump

China on Sunday (February 2) denounced the Trump administration's new tariffs on Chinese imports and threatened "countermeasures", but left the door open for talks with the U.S. that could avoid a deepening conflict. It came after Canada and Mexico responded to Trump slapping tariffs on their imports with retaliatory levies on U.S. goods, in what analysts say could lead to a trade war that slows global growth and reignites inflation.
