U.S. voices ‘Serious Concern’ after China conducts submarine-launched missile test in Pacific

The United States has expressed “serious concern” following China's test launch of a strategic missile from a nuclear-powered submarine into the Pacific Ocean, intensifying international attention on nuclear competition and arms control.

In a statement issued on Monday, the U.S. Department of State criticized Beijing after Chinese authorities confirmed that the launch involved a strategic missile equipped with a training, non-nuclear warhead. The test was conducted from a nuclear-powered submarine and directed toward the Pacific Ocean.

Washington argued that the launch comes at a time when the United States says it is working to curb the spread of nuclear weapons worldwide.

The State Department also voiced concern over what it described as the rapid and opaque expansion of China's nuclear arsenal, warning that the country's military buildup has implications not only for the Indo-Pacific but also for global strategic stability.

In response to the launch, the United States urged China to engage in meaningful arms control negotiations, reiterating its long-standing call for greater transparency regarding Beijing's nuclear capabilities and future modernization plans.

The missile test has drawn criticism from several countries across the Asia-Pacific region, reflecting broader concerns over rising military tensions and strategic competition in one of the world's most sensitive security environments.

The latest developments come amid growing uncertainty surrounding the international arms control framework. Earlier this year, Washington renewed calls for multilateral nuclear arms negotiations that would include China following the expiration of the New START treaty between the United States and Russia, previously the last remaining bilateral agreement limiting the strategic nuclear arsenals of the world's two largest nuclear powers.

U.S. officials have also accused both Russia and China of conducting undisclosed weapons testing, allegations that have contributed to deteriorating trust between the major nuclear powers.

Adding to the heightened strategic environment, President Donald Trump announced in October 2025 that the United States was preparing to resume nuclear weapons testing for the first time since 1992, describing the move as a response to testing activities by other countries.

China's latest missile launch underscores the increasingly competitive security landscape in the Indo-Pacific, where military modernization and nuclear deterrence continue to shape relations among the world's leading powers.
