U.S. chip controls face enforcement gaps

China’s government moved on May 13 to criticize a proposed U.S. semiconductor-equipment bill before expected talks in Beijing between President Donald Trump and President Xi Jinping, according to Reuters. The proposal, known as the MATCH Act, would tighten pressure on China’s access to chipmaking tools by targeting technology from the United States, Japan and the Netherlands, the report said. The public pushback came as U.S. prosecutors and other recent reporting pointed to a separate problem for Washington: advanced American chips and servers can still move through front companies, transit hubs and relabeling schemes after the rules are written. The gap is not the text of the controls alone, but the difficulty of stopping diversion once hardware enters global distribution channels. ### What did China object to before the Beijing talks? Reuters reported on May 13 that Beijing was pushing back against the MATCH Act before the Trump-Xi meeting in China. The bill would seek to close gaps in sales of semiconductor-manufacturing equipment to China by covering critical technology from the three countries that dominate that market — the United States, Japan and the Netherlands — according to the Reuters report. (usnews.com) The Chinese government had already signaled concern in April. Reuters reported that China’s Ministry of Commerce called U.S. chip industry representatives to its embassy in Washington to discuss semiconductor issues including the MATCH Act, and Chinese officials also raised the bill in pre-summit meetings, according to people cited by Reuters.

The U.S. Department of Justice said on March 19 that an indictment was unsealed charging Yih-Shyan “Wally” Liaw, Ruei-Tsang “Steven” Chang and Ting-Wei “Willy” Sun with conspiring to divert U.S.-assembled high-performance servers containing American artificial-intelligence technology to China in violation of export-control laws. Prosecutors said the defendants used front companies and concealed the true destination of the equipment. (klse.i3investor.com) The Justice Department said the case involved at least $2.5 billion of U.S. AI technology routed through Taiwan to China. CNBC, citing the indictment, reported that the products contained Nvidia chips and were subject to U.S. restrictions that bar sales to China without a license. (justice.gov) Super Micro said on March 19 that it was not named as a defendant in the indictment. The company said it placed Liaw and Chang on administrative leave and terminated its relationship with Sun, and said it would cooperate with authorities. ### Why do these cases matter even if the rules already exist? (justice.gov) The Commerce Department’s Bureau of Industry and Security said on October 17, 2023, that it had updated export controls to restrict China’s access to advanced computing chips and semiconductor-manufacturing equipment critical for military advantage. Those rules expanded the October 2022 controls and were designed in part to address circumvention risk. (ir.supermicro.com) The March 19 indictment shows the enforcement problem in concrete terms. Prosecutors alleged that restricted hardware was assembled in the United States, routed through intermediaries and sent onward to China anyway, despite the licensing regime already in place. Fortune separately reported on May 13 that encrypted messages described smuggling routes and tactics used to move Nvidia chips and other U.S. technology toward China, Russia and Iran. (bis.gov) That reporting could not be independently verified here from the original Fortune page, but it aligns with the Justice Department’s description of concealment, intermediaries and false destination information in the Super Micro case. (justice.gov) ### Where are the pressure points in the export-control system? Nvidia’s most advanced accelerators have become central because they power AI training and inference systems that governments view as strategically sensitive. BIS said its 2023 rules were intended to restrict the People’s Republic of China’s ability both to buy advanced computing chips and to manufacture advanced chips. (uk.finance.yahoo.com) Taiwan, Southeast Asia and other intermediary jurisdictions appear repeatedly in public allegations because servers, boards and complete systems can be sold through distributors and resellers before reaching the final user. The Justice Department’s March case alleged routing through Taiwan, while Reuters’ May 13 report showed Washington is also trying to tighten the equipment side of the supply chain through allied-country coordination. (bis.gov) ### What happens next? Reuters reported that the MATCH Act was likely to be raised in Beijing this week alongside the Trump-Xi meeting. The White House had not publicly taken a position on the bill as of May 13, Reuters said, and a White House official declined comment on pending legislation. (taipeitimes.com) The criminal case is also moving on a separate track. The Southern District of New York said Liaw, 71, Chang, 53, and Sun, 44, face counts including conspiracy to violate the Export Control Reform Act and conspiracy to smuggle goods from the United States, with arrests announced on March 19.
