Xinhua News Agency, June 12, Foreign Ministry spokesman Wang Wenbin held a regular press conference on 12 June. A reporter asked that data released by the Stockholm International Peace Research Institute in Sweden showed that in January this year, China's number of nuclear warheads increased by 61 over the same period last year, reaching 410. The institute points out that China is expanding its nuclear power. In addition, China has always said that nuclear forces should be maintained at the minimum level required for national security. does this idea change with the change of the security environment? How do you comment on this? Wang Wenbin responded that China has always adhered to self-defense and strategy, always maintained its nuclear forces at the lowest level of national security needs, and is not directed against any country. China abides by its policy of not being the first to use nuclear weapons at any time and under any circumstances, and undertakes unconditionally not to use or threaten to use nuclear weapons against non-nuclear-weapon states and nuclear-weapon-free zones. China is the only nuclear-weapon state that has adopted this policy, and China will remain firmly committed to safeguarding its own legitimate security interests and safeguarding world peace and stability.
