The United States and Germany cooperate in other international organizations besides NATO, including the anti-Islamic State Coalition of some 60 nations.
Berlin has been supportive of the Coalition that has carried out airstrikes against the ISIL in Iraq in August 2014, and in Syria in September 2014. Germany has also been sending weapons and military trainers to Kurdish Peshmerga fighters in Iraq.
"During the 45 minute meeting, the leaders discussed their continuing efforts in NATO and support to Iraq and Afghanistan," the statement, issued on Monday, said.
The two officials discussed ways to support NATO's collective defense measures against Russia's alleged involvement in the crisis in Ukraine, the statement specified.
