The People's Republic of China has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. The first of China's nuclear weapons tests took place in 1964, and its first hydrogen bomb test occurred in 1966 at Lop Nur .[ 3] Tests continued until 1996, when the country signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT), but did not ratify it.[ 4] China acceded to the Biological Weapons Convention (BWC) in 1984[ 5] and ratified the Chemical Weapons Convention (CWC) in 1997.[ 6] Since 2020, China has been wielding a nuclear triad ,[ 7] alongside four other countries .
The number of nuclear warheads in China's arsenal is a state secret.[ 1] There are varying estimates of the size of China's arsenal. The Bulletin of the Atomic Scientists and Federation of American Scientists estimated in 2024 that China has a stockpile of approximately 438 nuclear warheads,[ 1] [ 8] while the United States Department of Defense put the estimate at more than 500 operational nuclear warheads,[ 9] making it the third-largest in the world.
In 1964, China adopted a policy of no-first-use (NFU),[ 10] [ 1] although some of its nuclear forces are reported to have moved toward a launch on warning (LOW) posture in the 2020s.[ 11] [ 12]
