Efforts to achieve nuclear disarmament and non-proliferation are in crisis, according to German Foreign Minister Heiko Maas.
"It's a danger for world peace. We must counteract this negative development," Maas said on Tuesday in Sweden.
Maas is in Stockholm for a meeting of more than a dozen non-nuclear states, including Canada, Germany and Japan, in a bid to shore up support for nuclear disarmament.
"It's good that many states that want to hold on to and strengthen nuclear non-proliferation have come together today in Stockholm," Maas added.
