State the No First Use policy and its significance for China's nuclear posture.

• A. China pledges not to be the first to use nuclear weapons; aims to deter, preserve strategic stability, and avoid nuclear escalation.
• B. China reserves the right to use nuclear weapons preemptively in regional crises.
• C. China will never use nuclear weapons under any circumstances.
• D. China would only use nuclear weapons if attacked with nuclear weapons first.

Answer: (A)

The central idea being tested is what a No First Use pledge means and why it matters for China’s nuclear posture. No First Use is a commitment that China will not be the first to employ nuclear weapons in any conflict. This shapes deterrence by signaling restraint: other states know that China would only use nuclear weapons in retaliation to a nuclear attack or in a narrowly defined existential threat, not as an initial strike. That clarity helps reduce incentives for adversaries to strike first, since the act of initiating a nuclear exchange would not be seen as a preemptive option to gain advantage.

Significance lies in promoting strategic stability. By refraining from first use, China aims to prevent nuclear escalation from conventional crises and to keep the crisis management channel focused on deterrence and retaliation rather than anticipatory or preemptive action. It also aligns with a posture of minimum deterrence, prioritizing a credible second-strike capability to deter major powers while avoiding an expensive arms race. In practice, this policy communicates restraint to the international community, influences regional security dynamics in Asia, and lowers the likelihood that a regional crisis could spiral into nuclear exchange. It’s important to note that it does not promise never to use nuclear weapons under any circumstances; rather, it commits not to initiate use, relying on assured retaliation as the core of deterrence.
