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.

President Donald Trump on Tuesday warned that even more tariffs could be coming as soon as next week: This time China was his target, as Trump threatened to unleash a wave of higher taxes on imports from America’s second-biggest trading partner.

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