The US has blacklisted three companies and four subsidiaries of China’s National Supercomputing Centre, which the US accuses of building supercomputers to help its military.
This is the first step by the Biden administration to make it harder for China to influence US technology.
The blacklist prohibits American companies from exporting technology to the corporations concerned without proper authorization, and the seven Chinese corporations must get licenses to access US technologies, including chip infrastructures created by Intel and other US chipmakers.
The sanctioned groups are meant to advance China’s development of supercomputers and play an important role in China’s plan for self-sufficiency in chips.
The blacklist effectively prohibits US companies from supplying services and products to Chinese firms, but not those manufactured at plants outside the US.
Supercomputers have higher performance than normal computers and can perform billions of calculations per second, because they consist of thousands of connected processors used in many fields such as weather and climate forecasting, pharmaceutical research, the development of advanced weapons, and the simulation of nuclear tests.
