The recent declassification of US State Department documents has shed new light on the progression of events that led to the exposure of Taiwan's program to develop nuclear technology. It's a story in which the figure of ROC Colonel Chang Hsien-yi (
Chang was born in Taichung in 1943. After graduating from the military-run Chungcheng Institute of Technology in 1967, Chang began his career at the Institute for Nuclear Energy Research, a division of the Chungshan Institute of Science and Technology (
He was serving as deputy director of the nuclear research facility when he fled Taiwan on Jan. 9, 1988, just three days before the death of President Chiang Ching-kuo (
According to a military investigation after the incident, CIA personnel at the American Institute in Taiwan (AIT) arranged for his escape, under the silent consent of Taiwan's security agencies.
Chang allegedly kept his wife Hung Mei-feng (洪美鳳) and children in the dark about his defection. Two days after his escape, a CIA agent -- carrying a letter from Chang -- met his wife and children in Tokyo and escorted them to the US.
Immediately after his arrival in the US, Chang went to a secret Congress debriefing, where he confirmed the breakthroughs Taiwan had made in developing nuclear weapons -- and Taiwan's attempt to hide its nuclear program from US surveillance.
Chang's revelations prompted the US government to take tough action -- to pressure the Taiwan government to destroy its nuclear weapons facilities.
Chiang Ching-kuo's death did not change US pressure, and the Taiwan military finally gave in.
On Jan. 15, the US demanded access to the Institute for Nuclear Energy. Three days later, a team of US experts arrived at the Ching-chuankang air force base in Tai-chung. After a short discussion with Yeh Chang-tung (
After taking some soil samples and making an analysis of the hardware installed there, the US team started dismantling a heavy water reactor.
Within a few hours, the NT$1.85 billion facility and 17 years of research were decommissioned. If the costs for personnel training and software are taken into account, the military lost about NT$3 billion.
Later, Yeh traveled to the US and reportedly reached a consensus with US officials over Chang's defection.
After his escape, the Ministry of National Defense issued an arrest warrant for Chang, but later the Chungshan Institute completed paperwork to "discharge" him from service.

WAITING GAME: The US has so far only offered a ‘best rate tariff,’ which officials assume is about 15 percent, the same as Japan, a person familiar with the matter said Taiwan and the US have completed “technical consultations” regarding tariffs and a finalized rate is expected to be released soon, Executive Yuan spokeswoman Michelle Lee (李慧芝) told a news conference yesterday, as a 90-day pause on US President Donald Trump’s “reciprocal” tariffs is set to expire today. The two countries have reached a “certain degree of consensus” on issues such as tariffs, nontariff trade barriers, trade facilitation, supply chain resilience and economic security, Lee said. They also discussed opportunities for cooperation, investment and procurement, she said. A joint statement is still being negotiated and would be released once the US government has made
Authorities have detained three former Taiwan Semiconductor Manufacturing Co (TMSC, 台積電) employees on suspicion of compromising classified technology used in making 2-nanometer chips, the Taiwan High Prosecutors’ Office said yesterday. Prosecutors are holding a former TSMC engineer surnamed Chen (陳) and two recently sacked TSMC engineers, including one person surnamed Wu (吳) in detention with restricted communication, following an investigation launched on July 25, a statement said. The announcement came a day after Nikkei Asia reported on the technology theft in an exclusive story, saying TSMC had fired two workers for contravening data rules on advanced chipmaking technology. Two-nanometer wafers are the most
NEW GEAR: On top of the new Tien Kung IV air defense missiles, the military is expected to place orders for a new combat vehicle next year for delivery in 2028 Mass production of Tien Kung IV (Sky Bow IV) missiles is expected to start next year, with plans to order 122 pods, the Ministry of National Defense’s (MND) latest list of regulated military material showed. The document said that the armed forces would obtain 46 pods of the air defense missiles next year and 76 pods the year after that. The Tien Kung IV is designed to intercept cruise missiles and ballistic missiles to an altitude of 70km, compared with the 60km maximum altitude achieved by the Missile Segment Enhancement variant of PAC-3 systems. A defense source said yesterday that the number of
Taiwanese exports to the US are to be subject to a 20 percent tariff starting on Thursday next week, according to an executive order signed by US President Donald Trump yesterday. The 20 percent levy was the same as the tariffs imposed on Vietnam, Sri Lanka and Bangladesh by Trump. It was higher than the tariffs imposed on Japan, South Korea and the EU (15 percent), as well as those on the Philippines (19 percent). A Taiwan official with knowledge of the matter said it is a "phased" tariff rate, and negotiations would continue. "Once negotiations conclude, Taiwan will obtain a better
