How Beijing 'tripled the size of its nuclear arsenal' in six years

China's recent advancements in nuclear capabilities, including a long-range missile test from a nuclear-powered submarine, signal a significant escalation in its military power. Experts suggest Beijing has tripled its nuclear arsenal over the past six years, raising international concerns about regional and global security dynamics. This move not only underscores China's growing strategic influence but also prompts neighboring countries and global powers to reconsider their defense postures and alliances. The implications could shift the balance of power in Asia and beyond, with potential ripple effects on international relations and arms control efforts.
