"We have agreed to first look closely at the funds already available in the EU," Rutte said, referring to the discussion whether the EU needs fresh funds to support industries that could be hit by protectionist U.S. policies.

"And we have to see what the EU can do to make sure it is treated the way Mexico and Canada are treated, to resolve the unintended consequences on the side of the U.S."

Rutte added it could also make sense for the EU to loosen state aid rules for targeted industries such as green technology "in ways that support the internal market."
