As the White House fires a 10% tariff salvo, China sees room to negotiate.

President Donald Trump has finally made good on a campaign promise to raise tariffs on Chinese imports – announcing on Saturday duties of 10% on all Chinese goods coming in the country as part of sweeping trade measures that also targeted Mexico and Canada.

Robert Lighthizer, who was the U.S. trade representative in President Trump's first administration, says China poses an existential threat to the United States that must be urgently addressed by Washington.
