Sources: 15. Developments: 2. The United States and China have engaged in preliminary, informal discussions regarding reciprocal visits to nuclear facilities. These potential visits could include U.S. Department of Energy national laboratories and equivalent Chinese research centers, with some reports suggesting the possibility of accessing nuclear testing sites. While U.S. officials view these technical-level talks as confidence-building measures that could lead to broader trilateral arms control negotiations involving Russia, the Chinese Foreign Ministry has officially denied claims regarding the scope of these discussions, labeling them ‘completely inaccurate’. The talks occur amid heightened concerns over a global nuclear arms race following the expiration of the New START treaty in February 2026. While the United States maintains over 5,000 warheads, analysts note that China is expanding its arsenal at a faster rate than other nations, with estimates placing its stockpile at approximately 620 warheads in early 2026. ## Timeline ### 2026-10-08: US and China discuss potential nuclear site visits amid arms race concerns The US and China are reportedly discussing mutual nuclear site visits, though China has officially denied these claims amid concerns over a growing global arms race and China's expanding warhead stockpile. 2 sources. https://clstr.news/cluster/us-and-china-discuss-potential-nuclear-site-visits-amid-arms-race-concerns ### 2026-10-06: US and China discuss reciprocal visits to nuclear sites The U.S. and China are discussing reciprocal visits to nuclear sites and laboratories, a move that could serve as a building block for future trilateral arms control negotiations. 13 sources. https://clstr.news/cluster/us-and-china-discuss-reciprocal-visits-to-nuclear-sites --- Cite as: US-China nuclear facility visit discussions.
