Trump imposed sweeping tariffs on imports. In a ceremony at the White House Rose Garden, President Trump unveiled his most expansive tariffs to date yesterday, including tariffs of at least 10 percent on all trading partners except Canada and Mexico, with duties stretching past 20 percent, 30 percent and even beyond for some nations. European officials are poised to respond with countermeasures. Although the E.U. has so far concentrated on imposing higher tariffs on a wide variety of goods, officials have discussed placing penalties like tariffs or market access restrictions on U.S. technology companies and even limiting American banks' access to certain E.U. markets.
