The Trump administration is considering adding several major Chinese semiconductor companies to a U.S. export blacklist, a move that could further escalate tensions with Beijing and complicate ongoing trade negotiations. According to the Financial Times, the U.S. Commerce Department has drafted a list that includes ChangXin Memory Technologies (CXMT), a fast-growing memory chipmaker, along with subsidiaries of Semiconductor Manufacturing International Corp (SMIC) and Yangtze Memory Technologies Co (YMTC)—both of which are already subject to trade restrictions.
The potential action, spearheaded by the Commerce Department’s Bureau of Industry and Security, aims to curb China’s access to advanced U.S. chip technology amid concerns over its military applications. However, the timing has sparked internal debate within the administration, as the U.S. and China recently agreed to a temporary 90-day tariff rollback during talks in Geneva—a move seen as a stepping stone toward a broader trade deal.
Some officials fear that adding Chinese chipmakers to the “entity list” now could jeopardize the fragile diplomatic progress. Others argue the U.S. must prioritize national security and push forward with measures to block Beijing’s access to critical technologies.
“The debate reflects a broader divide between those focused on economic diplomacy and those advocating for a harder line on China’s tech ambitions,” the Financial Times reported.
CXMT has drawn particular attention from U.S. security officials due to its rapid expansion in the global DRAM market and its efforts to develop high-bandwidth memory (HBM), which plays a key role in powering artificial intelligence systems. The company is seen as a key player in China’s attempt to reduce dependence on foreign technology and strengthen its military modernization.
Blacklisting these firms would significantly limit their ability to procure U.S. technology. American companies are barred from selling to entities on the list without special licenses, which have become increasingly difficult to obtain. U.S. defense and intelligence officials have expressed concern that Chinese access to advanced semiconductors has aided efforts in hypersonic missile development and nuclear weapons modeling.
China’s response was swift but measured. The Chinese embassy in Washington said it “firmly opposes the US’s overstretching the concept of national security, abusing export controls, and maliciously blocking and suppressing China.” The companies named in the draft list declined or were unavailable for comment.
While the Commerce Department and the White House both declined to comment, the looming decision marks another flashpoint in the ongoing technological standoff between the world’s two largest economies. With U.S. officials divided over the risks to diplomacy versus national security, the fate of the proposed export controls may hinge on whether the administration prioritizes short-term trade goals or long-term strategic competition.
