China Submarine Missile Test Sparks Pacific Nuclear-Free Zone Row

China’s People’s Liberation Army Navy launched a submarine‑borne ballistic missile from off its coast that travelled roughly 7,000 km across the Pacific before splashing down near the island nations of Nauru and Tuvalu. The missile carried a dummy warhead and was described by Beijing as a routine exercise, but regional analysts say the flight path violated the spirit of the 1986 Treaty of Rarotonga, which establishes a South Pacific Nuclear‑Weapons‑Free Zone.

New Zealand’s foreign minister and Australian officials voiced concern that the test undermines the zone’s integrity, while the United States cited the launch as evidence of a growing Chinese nuclear capability and accelerated its own modernization of the nuclear triad, including new Columbia‑class submarines and the B‑21 bomber. The incident has heightened diplomatic tensions and prompted calls for clearer norms governing missile tests in nuclear‑free regions.
