China began producing highly enriched uranium (HEU) and plutonium for nuclear weapons in the 1960s and is believed to have halted production the 1980s. Despite the passage of thirty years there has been no official policy declaration in this regard. This report uses newly available public information from Chinese sources to provide an improved reconstruction of the history of China’s production of HEU and plutonium for nuclear weapons. This allows improved estimates of the amount of HEU and plutonium China has produced and of its current stockpiles.
