Is the world sliding into a new nuclear arms race?
According to a new report, it’s starting to look that way—and China’s rapid buildup is leading the charge.
By early 2025, China’s nuclear arsenal has reportedly hit 600 warheads, expanding by about 100 warheads a year since 2023.
That’s the fastest growth of any nation, says the Stockholm International Peace Research Institute (SIPRI).
And with 350 new ICBM silos either built or nearly finished, China could soon rival the US and Russia in missile numbers.
Beijing Shrugs Off The Race
“China always keeps its nuclear capabilities at a minimum level,” Foreign Ministry spokesman Guo Jiakun said.
He added that China has a “no first use” policy—something no other nuclear power formally declares.
But while China grows, the rest of the world isn’t standing still.

The US and Russia still dominate with around 5,000 warheads each.
Nuclear modernization is happening everywhere—from India and Pakistan to North Korea and Israel.
As arms control treaties crumble and tensions rise globally, SIPRI warns of a “dangerous new nuclear arms race.”
What’s more worrying? The weapons themselves—or the fact that so few nations seem eager to stop?
