ChangXin Memory Technologies (CXMT), China’s largest maker of DRAM chips, filed a lawsuit on Aug. 28, 2026, U.S. time, against the U.S. Department of Defense over its inclusion on a list of companies the Pentagon says are aiding Beijing’s military. The complaint asks the U.S. District Court for the District of Columbia to overturn the designation and remove CXMT from the roster, which can restrict government contracting and harm a company’s reputation. CXMT said it is not affiliated with the Chinese military and sells DRAM chips for civilian and commercial use. The Pentagon declined to comment on the pending litigation. CXMT was added to the list in January 2025 during the Biden administration, retained in a June update by the Trump administration, and relisted in June after the Pentagon withdrew a February 2026 notice that indicated the company would be removed. CXMT said the reversal lacked adequate explanation, violated due-process rights, and caused continuing commercial and reputational harm. The company’s first-half 2026 revenue rose 874% from a year earlier, Reuters reported in Japanese. The case follows Alibaba’s June lawsuit over the same type of designation and could influence how the Pentagon supports future listings and how companies challenge them, while complicating CXMT’s ambitions to enter the U.S. market.
