U.S. Commerce Secretary Howard Lutnick has expressed concerns that a highly sophisticated machine manufactured by Dutch semiconductor equipment maker ASML may have been shipped to China. The warning was delivered during a recent visit to ASML’s headquarters. Sources familiar with the matter, cited by Bloomberg, indicate the machine in question is among ASML’s most advanced technologies. This development raises fears about potential violations of export controls aimed at restricting China’s access to cutting-edge chipmaking technology. The U.S. government has been actively working to prevent China from acquiring tools necessary to advance its domestic semiconductor industry. ASML has not yet commented on the specific allegations, but acknowledged the meeting with Secretary Lutnick. Further investigation is expected to determine if export regulations were breached.
