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 Donald Trump said in an Oval Office signing ceremony Monday evening that his administration will impose 25% tariffs on Mexico and Canada on February 1, an extraordinary change in North American trade policy that could raise prices for American consumers.
