description: "US President Donald Trump has ordered HieFo Corporation, a Delaware-registered firm linked to China, to divest its semiconductor assets due to national security concerns. An executive order under the Defence Production Act cites credible evidence that HieFo's acquisition of EMCORE Corporation's digital chips could threaten US security. The order prohibits HieFo from retaining ownership of the assets and mandates divestment within 180 days, with oversight from the Committee on Foreign Investment in the United States (CFIUS). This action reflects increased scrutiny of Chinese investments in sensitive US sectors."

# Trump orders Chinese-linked firm to divest US semiconductor assets

US President Donald Trump has ordered the forced divestment of key semiconductor assets acquired by HieFo Corporation, a Delaware-registered company, which he said is controlled by a Chinese national, citing national security risks.\\nIn an executive order issued under the Defence Production Act, Trump on Friday said there was “credible evidence” that HieFo’s acquisition of EMCORE Corporation’s digital chips and related wafer design, fabrication and processing businesses could threaten US national security.\\n“There is credible evidence that leads me to believe that HieFo Corporation, a company organised under the laws of Delaware (HieFo) and controlled by a citizen of the People’s Republic of China … might take action that threatens to impair the national security of the United States,” Trump said in the order.\\nThe EO prohibits HieFo from retaining any ownership or rights in the EMCORE assets and gives the company up to 180 days to divest them, subject to oversight by the Committee on Foreign Investment in the United States (CFIUS). The transaction, completed on April 30, 2024, is effectively unwound.\\n\\n\\nUntil the divestment is completed and verified, HieFo is barred from granting access to the assets or any non-public technical information, and it faces strict restrictions on restructuring, transferring or relocating the business.\\nCFIUS is authorised to audit the company and impose additional measures to enforce compliance.\\nThe move underscores Washington’s heightened scrutiny of Chinese-linked investments in sensitive US semiconductor and advanced manufacturing sectors amid escalating geopolitical and technological competition with Beijing.\\nHeifo and Emcore did not immediately respond to a request for comment.\\nMore to follow...\\n
