The U.S. is edging closer to a trade war with China as President Donald Trump mulls whether to impose tariffs against imports of steel and aluminum.
Commerce Secretary Wilbur Ross outlined a number of potential tariffs and limits to Chinese metals, which are notorious for flooding markets at below standard prices.
But the reasoning behind these potential tariffs is raising eyebrows. Trump ordered an investigation into steel and aluminum imports on the grounds of national security. That opens the door to allow Trump to take whatever route he deems necessary.
China responded, saying the tariffs were "groundless" and it would take appropriate measures in response. Trade experts say invoking national security in order to impose protectionist tariffs could lead to other countries doing the same.
