The last of five nuclear-weapon states under the NPT, which at this moment possesses approximately 280 nuclear warheads in total. Nevertheless, the number of deployed bombs is unknown. The first test that occurred to be successful occurred in 1964. The main goal of Chinese was to build a deterrent against two major nuclear powers, namely The United States as well as The Soviet Union. The nation decided to choose dried lake for the nuclear site, Lop Nur. Although China developed and tested its first atomic device only in 1964, they managed to test their first hydrogen bomb only 32 months later. As a result, they can boast with the shortest period between developing fission and fusion technology.
China managed to conduct 45 tests of nuclear weapons. Still, the data regarding the stockpile of accumulated warheads is uncertain. The same thing concerns the number of deployed warheads. It is all due to the limited information that the country provides. We should also bear in mind that they are the only country out of five nuclear-weapon states under the NPT that does not give a positive security assurance.
