US senators have called for a national security review of Apple’s potential deal with Chinese state-owned storage chip maker Yangtze Memory Technologies Corp (YMTC), the Financial Times reported on Friday. Avril Haines, the US’s Director of National Intelligence, was asked to look at the deal and investigate how the Chinese authority utilizes TSMC to support the country’s semiconductor industry and replace other rivals from US or US-affiliated firms. Senators have also asked for the investigations to include an assessment of the role YMTC has played in helping Huawei and other Chinese firms bypass US sanctions, according to the report. Apple recently told the Financial Times that it was “evaluating” its use of YMTC’s chips for local iPhones but refused to comment on any potential investigation. The US has considered placing YMTC on a blacklist this year, in addition to discussing an export ban to China of equipment for 128-layer or more advanced storage chips. [Financial Times]
