China is on track to massively expand its nuclear arsenal, just as Russia suspends the last major arms control treaty. It augurs a new world in which Beijing, Moscow and Washington will likely be atomic peers.

WASHINGTON — On the Chinese coast, just 135 miles from Taiwan, Beijing is preparing to start a new reactor the Pentagon sees as delivering fuel for a vast expansion of China’s nuclear arsenal, potentially making it an atomic peer of the United States and Russia. The reactor, known as a fast breeder, excels at making plutonium, a top fuel of atom bombs.
The nuclear material for the reactor is being supplied by Russia, whose Rosatom nuclear giant has in the past few months completed the delivery of 25 tons of highly enriched uranium to get production started. That deal means that Russia and China are now cooperating on a project that will aid their own nuclear modernizations and, by the Pentagon’s estimates, produce arsenals whose combined size could dwarf that of the United States.
This new reality is prompting a broad rethinking of American nuclear strategy that few anticipated a dozen years ago, when President Barack Obama envisioned a world that was inexorably moving toward eliminating all nuclear weapons. Instead, the United States is now facing questions about how to manage a three-way nuclear rivalry, which upends much of the deterrence strategy that has successfully avoided nuclear war.
China’s expansion, at a moment when Russia is deploying new types of arms and threatening to use battlefield nuclear weapons against Ukraine, is just the latest example of what American strategists see as a new, far more complex era compared to what the United States lived through during the Cold War.
China insists the breeder reactors on the coast will be purely for civilian purposes, and there is no evidence that China and Russia are working together on the weapons themselves, or a coordinated nuclear strategy to confront their common adversary.
But John F. Plumb, a senior Pentagon official, told Congress recently: “There’s no getting around the fact that breeder reactors are plutonium, and plutonium is for weapons.”
It may only be the beginning. In a little-noticed announcement when President Xi Jinping of China met President Vladimir V. Putin in Moscow last month, Rosatom and the China Atomic Energy Authority signed an agreement to extend their cooperation for years, if not decades.
