Japanese auto stocks fell sharply after new U.S. tariffs against Mexico, Canada and China raised concerns about their U.S. sales of cars made in the North American trading partners and a further escalation in trade conflicts.

President Donald Trump signed an order to put tariffs on U.S. neighbors Canada and Mexico, as well as China, starting Tuesday.

China chose swift retaliation for trade measures in the first Trump administration, but that led to an upward spiral of trade measures and much broader tariffs.
