The US came out with new regulation at the start of October that has tightened the chip blockade on China. The new licence requirements limit items destined for Chinese fabs and supercomputer/ advanced logic end-users. These end users will no longer be able to access logic chips or equipment at 16 nm, or below, as well as high-end memory chips. US persons/entities can no longer support the development of the Chinese chip industry. And licences will face a 'presumption of denial'. The US also introduced a new rule that if US regulators are not given access to an unverified Chinese company within two months, then regulators will add the company to the dreaded entity list that crippled Huawei.
