A European Commission spokesperson says the EU will respond to new tariffs set to be announced by the US but it will happen at an "appropriate moment".

Speaking to reporters, Olof Gill says the EU is in "waiting mode" right now, but they have already conducted analysis into the possible impact tariffs will have.

They will deliver a two-step response, Gill says. The first will be on the steel and aluminium tariffs already in place, and a second which looks at everything else, he adds.

The first is currently in internal processes, and the second will be issued after today's expected announcement.
