France threatens EU retaliation over US plan for tariffs on cheese and Champagne

France has hit back at a US threat to slap 100% tariffs on French cheese, Champagne and other products, with the president telling Donald Trump the move would amount to an attack on all of Europe.

The US Trade Representative proposed the tariffs on €2.4bn of goods in retaliation for a French tax on global tech giants including Google, Amazon and Facebook.
