President-elect Donald Trump has just declared his intention that, on his first day in office, he will impose 10 per cent tariffs on all US imports from China, including those already subject to such levies.

China’s state media has warned U.S. President-elect Donald Trump against initiating a tariff war, following his pledge to impose additional tariffs on Chinese goods over fentanyl flows. Editorials in *China Daily* and *Global Times* caution that such a move could lead to a mutually destructive economic conflict between the world’s top economies.
