Lutnick should ban Chinese memory maker CXMT from U.S., Sen. Cotton says

Sen. Tom Cotton has asked Commerce Secretary Howard Lutnick to add Chinese memory manufacturer CXMT to the U.S. Entity List, citing the company's rapid expansion in DRAM and its push into high-bandwidth memory (HBM). The designation would restrict CXMT's access to U.S. technology and components, tightening export controls on China's semiconductor sector. CXMT has been gaining share in commodity DRAM and is positioning itself in HBM, a market currently dominated by SK Hynix, Samsung and Micron. The request signals growing congressional pressure on the Commerce Department to broaden restrictions beyond AI chips and equipment makers. Watch whether Lutnick's team acts on the recommendation and how any listing affects CXMT's HBM qualification timelines and global DRAM pricing.
