China's Technology Ambitions Challenged by US Chip Controls and Cybersecurity Probes.

China is struggling to retaliate against US efforts to cut off access to technology for advanced computer chips without hurting its own ambitions in telecoms, artificial intelligence, and other industries. China has its own chip foundries, but they supply only low-end processors used in autos and appliances. Making processor chips requires some 1,500 steps and technologies owned by US, European, Japanese, and other suppliers. The conflict has prompted warnings the world might decouple, or split into separate spheres with incompatible technology standards that mean computers, smartphones, and other products from one region wouldn’t work in others.
