WTO's Roberto Azevedo: We want to avoid a trade war
The Director General of the World Trade Organization Roberto Azevedo has told Stephen Sackur that President Trump's recent moves to impose trade tariffs are "a problem" and "no-one believes this is something minor".
Mr Azevedo said negotiations were on-going. "We want to avoid the war," he said.
President Trump has signed a proclamation authorising tariffs on foreign imports of aluminium and steel and has also said the US would place $60bn (£42.5bn) worth of tariffs on Chinese goods.
