Senator Chuck Schumer has teamed up with several of his Senate colleagues to demand Apple commit to not purchasing chips from Chinese companies ChangXin Memory Technologies (CXMT) or Yangtze Memory Technologies Co. (YMTC). The two companies are on the Defense Department's list of Chinese companies that are suspected to have ties to the People's Liberation Army. Schumer wants Apple to pledge not to use chips from CXMT or YMTC in any Apple product sold anywhere in the world. That's why I'm leading a bipartisan group of senators calling on Apple CEO Tim Cook to commit to not using memory chips produced by Chinese military-linked companies. Apple integrating these Chinese chips into its supply chain would send a dangerous message to other American companies that they, too, should turn to Chinese-made chips.
