The Trump administration has been negotiating North American trade in a deal dubbed the U.S.-Mexico-Canada Agreement (USMCA).

Trump said last week that he would suspend his plans to impose a 5 percent tariff on Mexican imports, which could have increased to 25 percent by October if his administration determined the country was not doing enough to prevent illegal immigration into the U.S. across the nations' shared border.
