Micron

Chinese authorities have launched an investigation into US memory chipmaker Micron Technology over national security concerns, according to an online notice by the country’s top cybersecurity regulator. The probe comes amid heightened competition between Beijing and Washington in the semiconductor field, as the US has sought to restrict exports of advanced chip technology to China. Micron said it was “cooperating fully” with Chinese authorities. The Netherlands and Japan have also recently imposed restrictions on exporting certain products to China, which Beijing has slammed as “US bullying tactics”.
