The heightened controversy between the PRC and the US caused by the recent visit to Taiwan by the Speaker of the American Parliament, Nancy Pelosi.
This step by an industry veteran, who until May 2012 was president of the British processor architect Arm, was reported by Bloomberg with reference to his personal comments on the social media pages LinkedIn. Tudor Brown admitted that he regretted the departure from the board of the Chinese contract chip manufacturer SMIC, where he had worked for the previous nine years.
According to Tudor Brown, international contradictions have only recently increased, forcing him to leave the board of directors of the Chinese company SMIC. It has recently become known that US export control regulations have been tightened, and now Chinese SMIC will not be able to obtain from any supplier lithographic equipment that uses American-based technologies suitable for producing 14 nm chips and more crudely, although previously the border was 10 nm. According to independent experts, this did not prevent SMIC from supplying components close to the 7-nm items of Taiwan TSMC from last summer.
