The most significant finding involves Chinese firms using shell companies or foreign representatives to bypass regulations that require government approval for any Chinese investment in Taiwan’s technology sector.
These investigations are critical to maintaining Taiwan’s "silicon shield," the strategic importance of its semiconductor industry which produces 90% of the world's most advanced chips.
Authorities argue that unauthorized Chinese operations facilitate talent poaching and the theft of intellectual property, threatening Taiwan’s economic competitiveness and national security.
By offering salaries up to ten times the local average, Chinese competitors have reportedly lured engineers into "undercover" labs to develop AI chips and other critical technologies, often leading to the unauthorized transfer of technical code to mainland team members.
The crackdown has led to dozens of convictions under the Cross-Strait Act, with high-profile raids targeting entities linked to major firms such as Xiaomi and SMIC.
To deter further activity, Taiwan recently tightened its National Security Act, introducing harsher penalties of up to 12 years in prison for the theft of "critical technologies." As global scrutiny of Chinese access to AI infrastructure and semiconductor expertise intensifies, Taiwanese prosecutors are increasingly focused on verifying the ultimate source of investment funds to prevent Chinese firms from using "indirect channels" to bypass international technological containment.
