A diplomatic source said that while the row was "a topic of concern for NATO", it was not a matter for the alliance to resolve. "It's not an alternative and it's not going to compete with NATO and, therefore, I welcomed the efforts to strengthen European defense and the EU efforts because I think that can strengthen NATO; it can strengthen Europe and the European Union, and by providing stronger European defense we can strengthen the European pillar within NATO and this has been clearly stated again and again also from European leaders".
But on Sunday a senior official working with Mattis said Washington had concerns that some of the proposed initiatives risked "pulling resources or capabilities away from NATO".

Mattis is to meet his Turkish counterpart on the sidelines of the meeting on Wednesday and Stoltenberg welcomed the fact that Turkey and the United States were talking directly.
The operation is being carried out under the framework of Turkey's rights based on worldwide law, UN Security Council resolutions, its self-defense rights under the UN charter, and respect for Syria's territorial integrity, it said.
