Military History of Taiwan - Nuclear Weapons Program

Nuclear Weapons Program

The development of nuclear weapons by the ROC has been a contentious issue, as it has been cited by the PRC as a reason to attack Taiwan. The U.S., hoping to avoid escalating tensions in the Taiwan Strait, has continually opposed arming the ROC with nuclear weapons. Accordingly, the ROC adheres to the principles of the nuclear Non-Proliferation Treaty and has stated that it does not intend to produce nuclear weapons. Past nuclear research by the ROC makes it a 'threshold' nuclear state.

In 1967, a nuclear weapons program began under the auspices of the Institute of Nuclear Energy Research (INER) at the Chungshan Institute of Science and Technology. The ROC was able to acquire nuclear technology from abroad (including a research reactor from Canada and low-grade plutonium from the United States) allegedly for a civilian energy system, but in actuality to develop fuel for nuclear weapons.

After the International Atomic Energy Agency found evidence of the ROC's efforts to produce weapons-grade plutonium, Taipei agreed in September 1976 under U.S. pressure to dismantle its nuclear weapons program. Though the nuclear reactor was soon shut down and the plutonium mostly returned to the U.S.

A secret program was revealed when Colonel Chang Hsien-yi, deputy director of nuclear research at INER who was secretly working for the CIA defected to the U.S. in December 1987 and produced a cache of incriminating documents. General Hau Pei-tsun claimed that scientists in Taiwan had already produced a controlled nuclear reaction. Under pressure from the U.S., the program was halted.

During the 1995-1996 Taiwan Strait crisis, then ROC President Lee Teng-hui proposed to reactivate the program, but was forced to back down a few days later after drawing intense criticism.
