Spanish Prime Minister Pedro Sánchez is sticking by his decision to break with NATO allies this week from spending more on defense.

"We're negotiating with Spain on a trade deal and we're going to make them pay twice as much," Trump said after the country refused to meet the spending target.

Spain said on Wednesday it did not expect any repercussions from its decision not to meet a defence spending target of 5% of gross domestic product that NATO member states are expected to set at a summit in The Hague.
