The EU has reverted to offering the US tit-for-tat tariff reductions on cars, with negotiators abandoning the idea of a complex “netting mechanism” first proposed by German carmakers.

The chief executive of Volvo Cars urged the European Union to cut its 10% tariff on American-made cars, arguing that European automakers do not need protection from U.S. competitors, in an interview with Reuters on Thursday.

EU trade ministers have agreed that U.S. President Donald Trump’s 30% tariffs announced on the European Union are “absolutely unacceptable,” and they are studying a new set of countermeasures to respond to the move.
