The US Bureau of Industry and Security (BIS) added seven Chinese aerospace electronics and related entities to its Entity List on Wednesday, restricting tech exports to them from US companies. BIS stated that the entities perform activities “contrary to US national security and foreign policy interests” by utilizing American tech “in support of China’s military modernization efforts.” According to BIS’s announcement, six out of the seven entities are technically research institutions, at least by name, that focus on aerotechnics, including both hardware and software. An analyst familiar with the field told Caixin that five of the seven entities listed had experience in aerospace semiconductor development, suggesting that the US is aiming to contain China’s development in this industry. China Aerospace Science and Technology Corporation (CASC) 9th Academy 772 Research Institute, for example, develops over 20 types of chips and 600 models used for airspace and military projects, according to Caixin. The latest addition brings the total number of Chinese entities on the list to 600, with more than 100 added since the start of the Biden administration. [Caixin, in Chinese]
