BRUSSELS (AP) — NATO's chief says the alliance and the European Union are moving forward on deepening cooperation, as U.S. President-elect Donald Trump insists European allies start pulling their own military weight.

NATO Secretary General Jens Stoltenberg told reporters before chairing talks between NATO foreign ministers Tuesday that "we have a momentum now."

He said NATO and the EU would endorse 40 proposals for boosting cooperation on cyber security and hybrid threats, operations at sea and helping neighboring countries better defend themselves.

Stoltenberg said "questions have been asked with respect to the strength of the trans-Atlantic bond" and that the best way to respond is to boost NATO-EU cooperation.

Trump lambasted Europeans during the U.S. campaign for not paying their fair share of defense budgets and wants NATO to do more against terrorism.
