In order to cut off the ability to develop their own chip industry, the United States imposed technology restrictions on China. Previously, only the sale of hardware and the licensing of chip technology were subject to barriers, with applications having to be approved by the United States Department of Commerce first. But through the latest order issued by President Biden, the citizens of the United States are also not allowed to work with Chinese chip companies.
This will have a major impact on China's chip industry as many top-level staff are US citizens. They now have to choose to stop working in China or choose to change citizenship. Among the efforts made by Beijing to improve its own chip development capabilities is to call home Chinese Americans who have expertise in this field.
The Biden administration, which was initially hoped not to continue the trade war agenda started by Donald Trump, is now seen as increasingly aggressive. More and more Chinese companies have been added to the list of entities including DJI recently because technology is believed to be shared with the Chinese People's Liberation Army. A few weeks ago, the export of artificial intelligence chips to China was restricted involving AMD and NVIDIA.
