On Thursday, March 19, 2026, DOJ announced an indictment unsealed in federal court charging Yih-Shyan âWallyâ Liaw, Ruei-Tsang âStevenâ Chang, and Ting-Wei âWillyâ Sun with conspiring to divert U.S.-assembled high-performance servers containing controlled AI technology to China.

DOJ says Liaw and Sun were arrested and would be presented in the Northern District of California; Chang remains a fugitive. ([justice.gov](https://www.justice.gov/opa/pr/three-charged-conspiring-unlawfully-divert-cutting-edge-us-artificial-intelligence))
According to the article text, the alleged pipeline used a purported end buyer in Southeast Asia, transshipment through Taiwan, relabeling/repackaging, and falsified documents to conceal China as the ultimate destination.
DOJ says the alleged scheme included âfalse documents,â âstaged dummy servers to mislead inspectors,â and âconvoluted transshipment schemes.â ([justice.gov](https://www.justice.gov/opa/pr/three-charged-conspiring-unlawfully-divert-cutting-edge-us-artificial-intelligence))
Supermicro stated it is not named as a defendant; it placed Liaw and Chang on administrative leave and terminated its relationship with Sun, and said it is cooperating with the investigation.

The article text asserts the value involved was about $2.5 billion in servers and describes alleged tactics (e.g., sticker/serial manipulation and dummy servers) that prosecutors say were used to evade compliance checks and government scrutiny.
The article text connects the criminal case to Supermicroâs prior governance/accounting disputes (including auditor turnover and prior regulatory scrutiny) as context for corporate-controls questions, but those issues are separate from the criminal charges described in the indictment.
DOJ quotes SDNY U.S. Attorney Jay Clayton saying the defendants allegedly used âa systematic schemeâ to divert âmassive quantitiesâ of AI servers to customers in China. ([justice.gov](https://www.justice.gov/opa/pr/three-charged-conspiring-unlawfully-divert-cutting-edge-us-artificial-intelligence))
