Trump Tariffs: China Hits Back With U.S. Penalties

China struck back against U.S. tariffs with levies on certain American goods, an antitrust probe into Google and restrictions on Chinese exports of key minerals. The moves escalated a new trade war between the world's two largest economies.

Just after American tariffs of 10% on China went into effect early Tuesday morning, Beijing said it would retaliate. Its measures will go into effect on Feb. 10. The Trump administration struck deals Monday to delay imposing new tariffs on Mexico and Canada.

President Trump said the tariffs on China were just "an opening salvo." He added: "If we can't make a deal with China, then the tariffs would be very, very substantial."
