BEIJING (Reuters) -China's state media warned U.S. President-elect Donald Trump his pledge to slap additional tariffs on Chinese goods over fentanyl flows could drag the world's top two economies into a mutually destructive tariff war.

While China could offset American tariffs by letting its currency fall, that might endanger Beijing’s recent efforts to stabilize the economy.

Trump announced plans to impose 10% tariffs on Chinese goods “above any additional tariffs,” after blaming the country for the inflow of illegal fentanyl into the U.S.
