China has always advocated a full ban and complete elimination of nuclear weapons, Defense Ministry spokesperson Yang Yujun said on Thursday.
The country that owns the largest nuclear weapon arsenals in the world should take special and primary responsibilities in nuclear disarmament, Yang said.
At the Xiangshan Forum in October 2016, armed forces of China and Russia announced they will hold a second anti-missile drill in 2017, aiming to exercise joint operation ability of air defense and anti-missile strength, Yang said.
