President Donald Trump said he would announce 25 percent tariffs on all steel and aluminum imports on Monday. The tariffs would apply to metals imported from all countries. But Trump did not say when the tariffs would take effect. In addition, he also said he would impose reciprocal tariffs on countries that would announce tariffs on U.S. imports later this week. Trump said the tariffs would not take effect on the same day as the announcement, possibly Tuesday or Wednesday, but would go into effect soon. (Jin Ten)
