President Donald Trump has taken the first step in imposing tariffs on nearly $50-billion worth of Chinese imports.
The order signed Thursday is aimed at punishing Beijing for stealing American technology and pressuring U.S. companies to hand it over.
The president is also asking Treasury Secretary Steven Mnuchin to come up with a list of restrictions on Chinese investment.
Trump says the U.S. and China have “the largest (trade) deficit of any country in the history of our world” and blames that deficit for lost American jobs.
He says the move will make the U.S. a “much stronger, much richer nation.”
China is already warning that it will take “all necessary measures” to defend itself, raising the prospect of a trade war between the world’s two biggest economies.
North American markets closed down sharply over fears of rising protectionism by moving to impose tariffs on some Chinese goods.
