Tech war: China hits back at American chip firms as regulator launches cybersecurity probe into Micron’s products
- It is the first time that the Chinese government has targeted a US semiconductor company
- Micron has previously warned investors of the risks of being excluded from the China market
China’s internet watchdog is launching a cybersecurity investigation into the local sales of US memory chip giant Micron Technology to “safeguard national security”, signalling an increase in tech tensions between the world’s two largest economies.
The Cyber Security Review Office under the Cyberspace Administration of China (CAC) said in a brief statement on Friday that the probe, which is the first ever into a foreign company by the office, has been launched to “safeguard key information infrastructure supply chain security” and to “prevent cyberspace security risks due to problematic products”.
It is also the first time that the Chinese government has targeted a US semiconductor company, as Washington tightens export controls on advanced chip products and equipment to China on national security concerns.
The CAC, which has gained enormous power in recent years to defend the country’s internet and information infrastructure, flashed its teeth with an investigation of Chinese ride-hailing giant Didi Chuxing in July 2021, levying a fine of 8 billion yuan (US$1.16 billion) after a lengthy probe.
However, until now, it has never launched an investigation into the products and services of a foreign company.
Micron has had a bumpy relationship with China in recent years as the country’s domestic memory chip makers, including Yangtze Memory Technologies Co (YMTC), have been expanding their operations.
The global dynamic random access memory (DRAM) market, Micron’s main product that accounts for nearly three quarters of its sales, currently has a supply glut with average DRAM prices down 20 per cent in the first quarter of 2023 compared to the previous quarter, according to TrendForce.
