A recent article from BBC News (1) indicates that the U.S. is concerned about the use by China of supercomputers to enhance their ability to design advanced weapon systems. Seven Chinese groups have been blacklisted. The measures have been initiated by President Biden in order to prevent the use of U.S. technology in the design, construction and operation of such computers.
These computers are used for various reasons, for both commercial and military applications. These different operations cannot be separated from each other. Supercomputers are used in the virtual design and testing of thermonuclear weapons and hyper-sonic aircraft, to name just a few worrisome aspects of their application.
China has been modernizing its military capabilities in recent years, and is already trying to seize the entire South China Sea for their own purposes. This area, valuable for raw materials and food, is largely open to all countries for navigation, and most of it falls under the 200 mile exclusive economic zones (2) for three countries: The Philippines, Vietnam and Malaysia.
The Chinese are violating international laws by dredging up "new land" in the South China Sea - clearly an attempt to control most of the area for their own purposes. The Chinese have no concern for the rights of other nations. These actions suggest they have no limits on what they deem appropriate for their grand plans for a future world, apparently under their control.
Does China represent a threat to the world with their activities to skirt international laws, and in modernizing their military to literally combat any push-back to their naked acts of aggression?!
