China Detonates Its First Atomic Weapon

On October 16, 1964, the People's Republic of China successfully detonated its first atomic bomb, thereby becoming the fifth country in the world to possess nuclear weapons.

China began its nuclear weapons program in the early 1950s, when it entered into several secret agreements with the Soviet Union to trade uranium mined in China for Soviet assistance in developing a Chinese atomic bomb. The Soviet assistance was substantial until the late 1950s when Sino-Soviet relations began to sour, and ended in 1960 with the withdrawal of Soviet advisors. Nevertheless, the Chinese pressed forward, although it took them some four years to achieve success. Their first atomic device, detonated at Lon Nor on October 16, 1964, resulted in an explosion of approximately 25 kilotons.

Following that event came other achievements, such as the launch of the first Chinese nuclear missile on October 25, 1966, and the successful detonation of the first Chinese hydrogen bomb on June 14, 1967. As of the writing of this book in the early 21st century, the exact extent of China's nuclear arsenal is unknown; it may range from several hundred to several thousand devices, but China is generally considered to be the world's third largest nuclear power after the United States and Russia (which inherited most of the Soviet arsenal after the Soviet Union broke up in 1991). Although the Chinese have pledged to observe a “no first use” policy, they are known to have a wide variety of devices for potential military uses, ranging from bombs and missiles capable of destroying whole cities to tactical battlefield weapons, such as nuclear land mines and artillery shells.
