French Economy Minister Bruno Le Maire on Tuesday promised a "strong" EU response to threatened US tariffs on French goods, as another front split open in the US trade war.

Axar.az reports citing AFP.

"We were in contact yesterday with the European Union to ensure that if there are new American tariffs there will be a European response, a strong response," Le Maire stated.

On Monday, the United States threatened to impose tariffs of up to 100 percent on $2.4 billion in French goods in retaliation for a digital services tax that Washington says is discriminatory.

The US and China are already embroiled in a trade war and US President Donald Trump said tariffs would be reinstated on Argentina and Brazil, accusing them of manipulating their currencies and hurting US farmers.
