China's navy has test-launched a long-range ballistic missile from a nuclear-powered submarine, showcasing its growing nuclear deterrence capabilities. The launch Monday has drawn protests from the U.S. as well as countries in Asia and the Pacific. Experts say the missile was likely a JL2 or JL3, both submarine-launched ballistic missiles. New Zealand has criticized the launch for violating the South Pacific Nuclear Free Zone. Australia and Japan have also expressed concerns, calling the act provocative. China's military expansion, including its nuclear arsenal, has increased tensions in the region, with security worries centered around Taiwan. The test highlights the ongoing militarization in Asia.
