Trump threatens to hit China with another 10% in tariffs as trade threats pile on

US President Donald Trump has threatened to ramp up tariffs on China and has mooted a 25% levy on the European Union as a relentless cannonade of trade actions continues.

By threatening to double tariffs on China to 20%, he cited his administration’s fight against drug smuggling as justification. He gave the same reason for his threat to end the tariff pause on Canada and Mexico.
