Taiwan is cracking down hard on Chinese firms secretly operating on the island to poach chip talent, a warning sign for anyone counting on Taiwan's dominance in advanced chips staying unchallenged.

• Taiwan's investigators have looked into 166 cases of illegally held Chinese assets since 2020, with at least 36 convictions so far.
• Almost all the convicted companies were doing chip design or research, hiding their Chinese ownership behind shell companies abroad or non-Chinese front men.
• Chinese firms have been luring Taiwanese engineers with pay five to ten times the going rate.
• US trade bans and export controls have pushed Beijing to speed up its drive to build chips without Western technology.
• Taipei treats this as a national security threat because its "silicon shield" — over 60% of global chip output and 90% of advanced processors — is what keeps allies invested in defending the island.

Outlook: Expect more prosecutions and tighter rules on Chinese investment as Taiwan tries to keep its chip lead from leaking across the strait.
