Overview
- Fresh geospatial analyses identify recent expansion and refurbishment at nuclear‑related facilities near Zitong and Pingtong in Sichuan.
- Experts say Zitong now includes new bunkers, ramparts and a complex dense with piping that is consistent with high‑explosive implosion testing.
- Analysts assess the double‑fenced Pingtong site, marked by a 360‑foot ventilation stack, as likely involved in producing plutonium warhead pits.
- Researchers report activity accelerating from around 2019 as part of a wider nuclear modernization, while the precise purpose and outputs remain unverified.
- U.S. officials have recently alleged clandestine Chinese nuclear explosive tests, a claim Beijing denies, as the Pentagon estimates China has over 600 warheads and could approach 1,000 by 2030.
