Global trade under threat

WHAT has gone on for decades of US trade deficits and uncompetitiveness to be unravelled with the imposition of steep tariffs on steel and aluminium?

Global trade is starting to look like a fight to protect each country’s turf with the US mounting more tariffs, first on washing machines and solar panels, and now on steel and aluminium that are used in heavy industries.
