Taiwanese prosecutors have detained two employees of US server maker Super Micro Computer along with a manager from Albatron, according to Bloomberg, following a raid this week of Super Micro's local offices over Nvidia shipments to China.

The detentions are part of a probe into the alleged smuggling of Nvidia's AI chips into China. According to Moneycontrol, investigators searched the offices of Super Micro, Albatron and Chief Telecom, and also raided the residences of all six people connected to the case.

The companies and individuals involved have not, in these reports, responded publicly to the allegations, and no charges tied to the Taiwan detentions have been detailed in the sources available.

The Taiwan action lands amid a wider regional crackdown on the movement of advanced AI chips. In a separate case, the Economic Times reports that Singapore police say suspects in an AI chip fraud investigation now face additional fraud and money laundering charges. Macau Business reports that Singapore authorities have seized a luxury bungalow as part of that probe.

Nvidia's most powerful AI processors are the engine behind the current boom in artificial intelligence, and the United States restricts their export to China on national security grounds. That has created strong incentives to route the hardware through intermediaries in places like Taiwan and Singapore, and mounting pressure on those governments to police the trade.

Why it matters: the cases show that enforcement of US chip controls is spreading beyond America's borders into the Asian supply hubs where the world's most sought-after AI hardware is built and shipped.
