President Trump said on Tuesday that he intended to impose a 10 percent tariff on Chinese imports into the United States on Feb. 1, a decision that is sure to escalate trade tensions between the world’s largest economies.

Trump underscored his intention to use tariffs as a tool of international economic policy and an increasingly vital source of government revenue.

President Trump said Monday that he expects to put 25% tariffs on Canada and Mexico starting Feb. 1, while declining to flesh out his plans for taxing Chinese imports.
