The decision is a further blow for the already-ailing Eurozone and global economies, although not as severe a blow as it could have been.
"We've been arguing for a trade deal for months".

The two cases are expected to lead to tit-for-tat tariffs, beginning with the USA measures, posing new problems for businesses and financial markets around the world.
