Implications of Chinese Nuclear Weapons Modernization for the United States and Regional Allies

John Lee & Lavina Lee

Based on current trends, China will become a quantitative and qualitative nuclear weapons peer of the United States by the early to mid-2030s with a diversified, accurate, and survivable force that will rival America’s. Rather than having only high-yield nuclear missiles as a strategic deterrent against nuclear attack, the People’s Liberation Army (PLA) is developing a range of strategic and tactical nuclear weapons, the latter being lower-yield weapons usable in a conflict theater.

Why is China seemingly going beyond its long-standing nuclear weapons approach of maintaining only a minimal deterrent or assured retaliation? Why has it chosen to rapidly develop its nuclear arsenal and related delivery system in a deliberately opaque manner?

This report argues that Xi Jinping and the Chinese Communist Party (CCP) decided to embark on such a rapid nuclear modernization not primarily because China wants to “win” a nuclear exchange against the US. Rather, Beijing wants to create political and psychological effects that lead to enormously important strategic and military effects.

As the report explains, the CCP and PLA are using the rapid development of nuclear capability and related delivery systems to subdue the adversary and win without fighting. The following are components of achieving this:Degrade the adversary’s decision-making.

Weaken the adversary’s will to fight.

Undermine the adversary’s public support for war.

Undermine the resolve of the adversary’s government from within.

Support and enhance deterrence.

The report assesses that there are three ways in which China uses nuclear modernization to change the material and psychological environment with important strategic effects that work to its advantage.
