The U.S. proposed an additional 89 “tariff subheadings” listing $4 billion worth of European goods that could be subject to additional tariffs, Bloomberg News reports. The U.S. trade representative reportedly wants to “enforce U.S. rights in the World Trade Organization dispute against the European Union” after both the U.S. and EU have accused each other of “illegally subsidizing” aircraft makers. The proposal lists “cheese, milk, coffee... Irish and Scotch whiskies,” certain metal products, and pork products.
