"At last week's defense ministerial meeting, we also discussed U.S. military presence in Europe, particularly in light of the U.S.plan to reduce its presence in Germany," Stoltenberg said in welcoming remarks.

Esper and Stoltenberg discussed the importance of fighting an expected second wave of the pandemic, arms control, recent Russian actions regarded by NATO as destabilizing and "the importance of key partnerships," a Defense Department statement on Friday said.
