China warned the Trump administration on Tuesday against reigniting trade tension by restoring tariffs on its goods next month, and threatened to retaliate against nations that strike deals with the United States to cut China out of supply chains.

China accounted for 5.89% of all U.S. trade in May, its lowest percentage in decades. Trump’s tariffs or trade trickery? It’s hard to dispute it’s a remarkable shift.

Long before President Trump wielded tariffs as a weapon to punish Indonesia, the country was fighting back a flood of cheap Chinese goods.
