Europe, Canada and Mexico are planning retaliatory meowes after President Trump imposed tariffs on steel and aluminium imports to the US.
The European Union issued a 10-page list of tariffs on US goods ranging from Harley-Davidson motorcycles to food products.
It also plans to challenge the move at the World Trade Organization.
Mr Trump claimed the tariffs would protect US steelmakers, which were vital to national security.
French President Emmanuel Macron called Mr Trump to tell him the tariffs were “illegal” – a term echoed by Bernd Lange, chair of the European Parliament’s international trade committee.
