Trump Cancels Sale of US Chips Business to Chinese Firm Over Security Concerns
.
WASHINGTON—President Donald Trump issued an order Friday canceling HieFo Corporation’s acquisition of chips and wafer fabrication assets from Emcore Corp. in 2024, citing national security concerns.
The president said in the order that “there is credible evidence” showing HieFo, through its acquisition of Emcore’s assets, “might take action that threatens to impair the national security of the United States.”
The company has 180 days to divest all these assets, according to the order, unless the date is extended by the Committee on Foreign Investment in the United States (CFIUS). The committee is an interagency body that reviews foreign investments in the United States to assess potential national security risks.
HieFo and its affiliates, according to the order, will be forced to “divest all interests and rights in the Emcore Assets, wherever located, including contracts, inventory, tangible property, parts, fixed assets, accounts receivable, permits, real property leased or owned by EMCORE Corporation, and intellectual property.”
In the statement, Genzao Zhang and Harry Moore were listed as co-founders of the new company. Zhang, former vice president of engineering at Emocre, has been named CEO of HieFo.
“By leveraging more than four decades of innovative legacy in optoelectronic devices from EMCORE, we will continue the pursuit of the most innovative and disruptive solutions to serve telecom, datacom, and AI connectivity industries,” Zhang said in the statement. “With the experienced core team and strong financial backing, we will be resuming the operations very rapidly.”
This was not the first time Trump blocked a deal.
According to the memorandum, the United States will use all legal instruments, including the CFIUS, to limit Chinese investments in key sectors such as technology, critical infrastructure, health care, agriculture, energy, and raw materials.
