China Flag for China

In 1964 China became the world’s fifth nuclear-weapon state; the last to be recognized under the Nuclear Nonproliferation Treaty (NPT). China has recently increased its warhead count while modernizing its strategic missile forces and nuclear submarine fleet, making its stockpile the world’s third largest (although much smaller than that of the U.S. or Russia).
