Investment bank Investec said in a note: "The trade war in the global steel industry is hotting up — and it is not all about China, despite massive Chinese overcapacity and resultant exports."
It continued: "It is difficult to see where this will end but former major steel producers such as the US and the UK have to decide if they wish to maintain a domestic steel industry or whether they wish to become totally dependent on imported steel."

Gareth Stace, director of UK steel, told City A.M.: In the short-term, we are going to see more trade defence instruments being implemented by a range of countries."
He added that this trend will continue until the fundamental problem of overcapacity in the global steel industry is resolved.
