Beijing, November 14, 2025 — China issued a sharp diplomatic warning to the United States on Thursday, cautioning that any American move to resume nuclear weapons testing could trigger a destabilizing new global arms race, further inflaming already tense US–Russia relations.
The statement from Beijing follows signals from Washington that it may reconsider nuclear test protocols amid escalating strategic friction with Moscow. China’s foreign ministry said such a shift would have “grave consequences for global security,” stressing that nuclear restraint is essential to prevent a dangerous escalation spiral.
Beijing’s Message: Nuclear Tests Could Force China’s Hand
In an unusually direct comment, Chinese officials hinted that Beijing could be compelled to conduct its own nuclear tests if the US breaks longstanding norms.
A senior Chinese diplomat said:
“If the United States undermines the global moratorium on nuclear testing, China will take all necessary measures to safeguard its national security interests.”
Experts note that China has been modernizing its nuclear arsenal but has not conducted an open nuclear test since 1996, adhering to the global testing freeze despite not formally ratifying the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
Global Stakes Rise as US–Russia Tensions Deepen
Washington’s review of its nuclear posture comes amid worsening relations with Russia, which has accused the US of attempting to “strategically dominate” nuclear thresholds. Russia withdrew its CTBT ratification in 2023, heightening concerns that the world’s major nuclear powers could drift toward competitive testing.
Analysts warn that a renewed cycle of nuclear demonstrations could pressure other nuclear states, particularly China and India, to recalibrate their deterrence doctrines.
Arms Race Fears: A Return to Cold War-Era Instability?
According to the Stockholm International Peace Research Institute (SIPRI), the world’s nuclear warhead inventory is already on a slow upward trend, with global modernization programs increasing for the first time in decades. A nuclear test revival, experts say, could accelerate that trajectory.
A global security researcher noted:
“We are entering a phase where nuclear signaling is becoming sharper, riskier, and more public. A US test would give political cover for others to follow.”
China Calls for Strategic Stability
Beijing urged Washington to “exercise restraint” and reaffirm its commitment to nuclear non-proliferation norms. The Chinese government emphasized that dialogue — not demonstrations of nuclear capability — is the only path to restoring global stability.
What Happens Next?
The US has yet to announce any formal decision, but senior Pentagon officials say all options remain “on the table” amid rising geopolitical pressure.
Observers warn that any shift could reshape nuclear politics for years to come — with China’s response now a key variable in a rapidly evolving strategic landscape.
