China is rapidly expanding and modernizing its nuclear arsenal, currently possessing approximately 600 warheads and constructing around 350 new missile silos. The United States projects that Beijing's nuclear stockpile could exceed 1,000 warheads by 2030. This expansion includes the development of several new bases for road-mobile launchers. Despite China's official commitment to a "no first use" nuclear policy, the Pentagon has expressed concerns that China might reconsider this stance. The increase in China's nuclear capabilities reflects the fastest growth among nuclear-armed powers since 2018, during which China added about 360 warheads to reach its current total. Concurrently, China is also advancing its nuclear energy sector, with 29 reactors under construction, outpacing other countries such as India, Russia, Egypt, and Turkey. In response to China's growing military threat, some U.S. analysts advocate for the establishment of a collective defense pact in Asia. The ongoing expansion has sparked strategic debates about whether China's nuclear buildup is a calculated move or a political gamble.
