"The Cold War mentality must be eradicated before nuclear weapons can be totally eliminated," said Geng Shuang, China's deputy permanent representative to the United Nations, on Tuesday. "With such a mentality, the world cannot achieve real nuclear disarmament and will not enjoy real peace and tranquility." Geng's comments were made at the high-level plenary meeting of the General Assembly to commemorate and promote the International Day for the Total Elimination of Nuclear Weapons.
