The U.S. is considering tariffs on an additional $4 billion worth of goods from the European Union.
It's over what it considers to be illegal aircraft subsidies. Whether the tariffs happen depends on the results of a World Trade Organization assessment of E.U. subsidies on large civil aircraft.
The U.S. Trade Representative's Office disclosed it could target a further 89 sub-categories following an earlier list in April. The new items include cheeses, olives and coffee.
