Two leading Republicans on Tuesday urged the Trump administration to strengthen the new rules passed on Friday, aimed at preventing China’s largest chip manufacturer SMIC from gaining access to advanced US technology.

Senator Marco Rubio and Representative Michael McCaul stated that the list of entities designated by the U.S. Department of Commerce is not strict enough and should be rewritten to close “dangerous loopholes, which will enable almost all alignments.” Chips International’s sales can continue unrestricted, and support (the Communist Party of China) clarified the goal of military superiority.” The letter said that they fear that if no changes are made, the rules will “have an impact on solving this growing national security threat. Completely invalid”.

The U.S. Department of Commerce declined to comment, but Secretary of Commerce Wilbur Rose said on Friday that this appointment is “to ensure that China, through its national champion SMIC, cannot use U.S. technology to support its turbulence. Necessary measures for military power. Activities.”

Lawmakers are worried because these restrictions only apply to the “only” technology required to produce semiconductors of 10 nanometers and below. They wrote that the government “seems to allow SMIC access to almost all semiconductor manufacturing equipment.”

The lawmakers expressed that they were worried that the new regulations were “made for performance and commercial interests, but they would harm the national security of the United States.”

SMIC said on Sunday that being included in the U.S. trade blacklist would have a major adverse impact on its research and development of 10nm and more advanced chip technologies, but said it did not expect the US decision to have a major negative impact on its products. Short-term operations and finances.
