Biden had arrived to tout the company’s newly announced $40 billion investment in U.S. microelectronics manufacturing following the July enactment of the CHIPS Act, which included $52 billion in subsidies and tax incentives for businesses that produce semiconductors within the country.But left out of Biden’s Arizona speech is a similarly urgent effort the U.S. government is undertaking to slow China’s advancements, including new restrictions that limit Beijing’s access to these highly sophisticated chips.“This severely limits China’s ability to access advanced nodes or build its own capabilities,” said Jay Goldberg, a specialist on Asia’s electronics supply chain and the chief executive of D2D Advisory, a consulting firm.Biden’s export controls greatly expand the Trump-era restrictions; they require U.S. microelectronics companies, or foreign businesses that use American technology, to obtain licenses from the Commerce Department to sell to Chinese firms the equipment needed to produce the most advanced semiconductors — licenses Washington is unlikely to grant.Goldberg said the export controls hinder the Chinese military’s ability to build “advanced capabilities into their systems.” “Especially for the Chinese military, the really limited things will be around supercomputing, which is really important for weapons design, for nuclear weapons simulation, advanced weather modeling, those kinds of things,” he explained."
