UPDATE 1-China import concerns spur US to launch semiconductor supply chain review

The U.S. Department of Commerce said Thursday it will launch a survey of the U.S. semiconductor supply chain and national defense industrial base to address national security concerns from Chinese-sourced chips. The survey aims to identify how U.S. companies are sourcing so-called legacy chips – current-generation and mature-node semiconductors – as the department moves to award nearly $40 billion in subsidies for semiconductor chips manufacturing. The department said the survey, which will begin in January, aims to "reduce national security risks posed by" China and will focus on the use and sourcing of Chinese-manufactured legacy chips in the supply chains of critical U.S. industries.
