In a significant legal move, federal prosecutors have brought charges against three men associated with Super Micro Computer Inc. for allegedly orchestrating a massive operation to illegally transport billions of dollars’ worth of U.S. artificial intelligence technology to China. The scheme reportedly involved the use of counterfeit documents, shell companies, and staged equipment to achieve its ends, according to officials.
The accused are said to have rerouted AI servers valued at $2.5 billion to China, with an astonishing $510 million worth of equipment being transferred in just a few weeks during 2025.
Authorities arrested Yih-Shyan Liaw, a 71-year-old U.S. citizen, and Ting-Wei Sun, aged 44 from Taiwan, this past Thursday. However, Ruei-Tsang Chang, a 53-year-old also from Taiwan, remains at large.
Assistant Attorney General for National Security John A. Eisenberg commented on the case, stating, “The indictment unveiled today outlines alleged attempts to bypass U.S. export regulations through deceptive documentation and mock servers designed to mislead inspectors. These complicated transshipment tactics were intended to disguise the real destination of the controlled AI technology—China. These chips are a testament to American innovation, and the National Security Division is committed to enforcing our export-control laws to protect that edge.”
Prosecutors have accused three individuals linked to Super Micro Computer Inc. of attempting to smuggle substantial quantities of U.S. AI technology to China under the guise of legitimate transactions.
Supermicro said Thursday it was informed by the U.S. Attorney’s Office for the Southern District of New York that three individuals associated with the company had been indicted in connection with an alleged export-control scheme. The company said it is not named as a defendant.
Supermicro said Liaw was a co-founder, senior vice president of business development and board member, Chang was a sales manager in Taiwan, and Sun was a contractor.
Supermicro said it placed the two employees on administrative leave and terminated its relationship with the contractor.

“The conduct alleged in the indictment violates the company’s policies and efforts to comply with export control laws,” Supermicro said.
According to the indictment, Liaw and Chang — who worked with brokers and customers in China — allegedly directed executives of a Southeast Asia-based company to place purchase orders with a U.S. manufacturer for servers equipped with certain GPUs, purportedly for that company.
The servers were often assembled in the U.S. before being delivered to the Southeast Asia-based company, which then repackaged them in unmarked boxes to conceal their contents before shipping them to China.

The defendants and company executives allegedly prepared false documents and communications to show that the company was the end user of the servers.
U.S. Attorney Jay Clayton for the Southern District of New York accused the defendants of participating in a “systematic scheme” to divert servers with U.S. artificial intelligence technology to customers in China.
“They did so through a tangled web of lies, obfuscation, and concealment—all to drive sales and generate revenues in violation of U.S. law,” he said. “Diversion schemes like those disrupted today generate billions of dollars in ill-gotten gains and pose a direct threat to U.S. national security.”

Roman Rozhavsky, assistant director of the FBI’s Counterintelligence and Espionage Division, added that “controlling the export of sensitive U.S. artificial intelligence technology is essential to safeguarding our national security and defending the homeland.”
Prosecutors said the defendants took “extensive measures” to conceal the scheme.
According to the indictment, the defendants staged thousands of “dummy” servers — nonworking physical replicas of the U.S. manufacturer’s servers — to deceive its compliance team.
Officials said surveillance video captured the defendants preparing the dummy servers in a warehouse. Ahead of an inspection by the U.S. Department of Commerce, they allegedly used a hair dryer to remove and reapply labels and serial number stickers to server boxes and the dummy servers.
They then repackaged the dummy servers in the U.S. manufacturer’s boxes, according to the indictment.
The defendants were charged with conspiracy to violate the Export Control Reform Act, which carries a maximum sentence of 20 years, as well as conspiracy to smuggle goods and conspiracy to defraud the United States, each carrying up to five years.
