U.S. and China Clash Over Nuclear Arms Control at NPT Review Conference; China Rejects Multilateral Talks
⚡ What Happened
At the NPT Review Conference, the United States condemned China's multi-fold expansion of nuclear forces and demanded its participation in multilateral arms control talks, but China rejected the proposal as a "political posture." The rift between the U.S. and China over nuclear arms control was once again laid bare, and the dysfunction of existing disarmament frameworks is growing increasingly severe. While informal contacts between the two sides may be explored before the next conference, the prospects for formal talks remain extremely slim.
China has rapidly increased its nuclear warhead count since the 2020s, and the U.S. Department of Defense has estimated the arsenal could reach approximately 1,500 warheads by 2035. The existing bilateral U.S.-Russia disarmament framework (New START, etc.) cannot capture China, prompting the U.S. to seek a transition to a multilateral framework. However, China has consistently maintained the position that "there is no reason to engage in arms reduction negotiations on equal terms at a stage when its warhead count is far below those of the U.S. and Russia." The public condemnation at this NPT Review Conference is part of a U.S. strategy to rally international opinion and pressure China, but for China, nuclear deterrent modernization is a core security interest directly linked to the Taiwan issue and its Indo-Pacific strategy, leaving extremely little room for concessions. This signals a structural turning point in which U.S.-China strategic competition has fully expanded into the nuclear domain.
🔍 The U.S. multilateral talks proposal is less about feasibility and more an information warfare effort to internationally isolate China as a "major power uncooperative on disarmament." The U.S. side has already factored in China's refusal, and the refusal itself serves as material to rally allied unity. Meanwhile, China's "political posture" remark reflects the perception that the U.S. proposal is merely a means to check China's nuclear modernization rather than a genuine negotiation on equal footing. In essence, neither country currently has an incentive to reach a nuclear arms control agreement, and the NPT forum is being used as a stage for great-power politics.

🔮 Next Scenarios
🎯 Incentive Map
| Player | True Incentive | Underlying Vulnerability | Predicted Action |
|---|---|---|---|
| U.S. (Post-Biden Administration) | Isolating China internationally while strengthening allied unity. Building a pressure narrative against China takes priority over actual disarmament agreements | Domestic political need for a hardline stance. Military-industrial complex interests and justification of nuclear modernization budgets | Continue condemning China at multilateral forums such as the NPT while simultaneously advancing nuclear sharing and extended deterrence with allies |
| China | Avoid arms reduction negotiations until nuclear forces approach parity with the U.S., and complete nuclear modernization | Balancing nuclear escalation risk management on the Taiwan issue with concerns over international isolation | Reject multilateral talks while maintaining moral high ground with the argument that "the U.S. and Russia should make major reductions first" |
| NPT Non-Nuclear Weapon States (Japan, Europe, etc.) | Reconciling two contradictory goals: advancing nuclear disarmament and maintaining the credibility of extended deterrence | Caught between dependence on the U.S. nuclear umbrella and pressure from states supporting the Treaty on the Prohibition of Nuclear Weapons | Support the U.S. multilateral talks proposal while seeking to maintain independent dialogue channels with China |
⚠️ Pre-Mortem — Conditions Under Which This Prediction Fails
- An unexpected political compromise is reached at a U.S.-China summit or similar venue, and China announces conditional participation in talks
- Military tensions in the Taiwan Strait or elsewhere escalate sharply, prompting both countries to urgently launch nuclear risk reduction dialogue to avert a crisis
- Underestimation bias regarding China's nuclear forces: the possibility that China gains more confidence than expected, creating room to engage in negotiations, is being overlooked
Fear-Setting / When this prediction fails
- This probability fails if a US-China summit produces a surprise agreement on nuclear risk reduction talks before June 2026.
- This probability fails if a major military crisis (e.g., Taiwan Strait incident) forces emergency bilateral nuclear dialogue that evolves into formal multilateral participation.
- This probability fails if China uses multilateral arms control participation as a bargaining chip in trade negotiations, accepting the proposal for unrelated concessions.
HIT Condition: HIT if China does not formally announce participation in U.S.-proposed multilateral nuclear arms control talks by the end of June 2026
Resolution Date: 2026-05-14
