China is rapidly expanding and modernizing its nuclear arsenal, currently estimated to include about 600 warheads, according to Reuters and U.S. military sources. The country is constructing approximately 350 new missile silos and several bases for road-mobile launchers. U.S. forecasts project that China could possess more than 1,000 nuclear warheads by 2030. Despite China's official "no first use" policy, the Pentagon has raised concerns that Beijing might reconsider this stance. Additionally, China has criticized the Trump administration's proposed next-generation strategic missile defense system, known as Golden Dome, arguing that it threatens strategic stability and undermines mutual deterrence. These developments highlight an ongoing arms race and growing tensions over missile defense and nuclear capabilities.
