The Chinese government ordered all government offices and public institutions to replace foreign hardware and software with Chinese solutions within the next three years. The directive doesn’t apply to privately-owned Chinese companies, that will be authorized to continue using foreign technology. The replacement process will start in 2020 with the goal to replace 30% of their foreign software and 30% foreign hardware. 20m-30m pieces of hardware will need to be replaced in compliance with the Chinese directive, most of them beginning next year. US technology companies generate as much as $150bn a year in revenues from China.”]
