China accelerates nuclear weapons programme at seven strategic sites

China is rapidly expanding its nuclear weapons programme, with fresh activity detected at seven strategic sites across the country. Construction and upgrades have been observed at facilities including Pingtong, Zitong and the long-established test and development complex at Lop Nur.

The country is estimated to possess approximately 620 nuclear warheads, a figure that analysts believe could grow further as Beijing moves to equip new delivery systems with warheads. The scale and pace of development signals a significant acceleration in China's strategic ambitions.

The simultaneous activity across multiple sites suggests a coordinated, nationwide push to modernise and enlarge the arsenal, raising fresh questions about regional stability and the future of arms-control efforts.
