Trump blocked Chinese investors from acquiring a US firm

U.S. President Donald Trump blocked a transaction in which the Chinese company HieFo was to acquire assets of the American company Emcore, Reuters reported. The White House order indicated that HieFo is "controlled by a citizen of the People's Republic of China." Trump stated that a previous, finalized 2024 acquisition of Emcore's businesses by HieFo could have led to actions "threatening the national security of the United States." A Treasury Department statement, issued after the president's decision, confirmed that the Committee on Foreign Investment in the United States (CFIUS) had identified a risk to national security during its proceedings, though no details of the threat were provided. Trump wrote in the decision: "The transaction is hereby prohibited," and HieFo must "divest all interests in and rights to Emcore's assets, wherever located," within 180 days of the order's issuance
