China's Commerce Minister Wang Wentao last week had a meeting with Sanjay Mehrotra, chief executive of Micron, expressing support for the company's expansion in China, reports Reuters. Meanwhile, there is no word whether the People's Republic is going to lift a ban on Micron's memory devices that are used for PCs used by government-controlled agencies and critical infrastructure.
"We welcome Micron Technology to continue to take root in the Chinese market and achieve better development under the premise of complying with Chinese laws and regulations," Wang said.
Micron is one of the companies that does not produce chips in China, but which has vast packaging operations in the country. The company's 3D NAND and DRAM memory ICs, made Singapore and Taiwan, are then packaged in China and distributed to makers of memory modules and solid-state drives, including the best SSDs with a PCIe 5.0 x4 interface.
Micron's China operations are vast. Back in June the company announced plans to invest some additional $600 million in its facilities and add 500 more jobs, increasing its headcount in the country to more than 4,500.
But the massive facilities that that Micron runs in China did not stop the People's Republic's government from banning its chips following a security assessment conducted by Cyberspace Administration of China (CAC). The organization concluded that Micron's products "have relatively serious potential network security issues, which pose a major security risk to my country's critical information infrastructure supply chain."
But CAC did not elaborate on the exact security threats that Micron's products may pose in particular and how a memory IC can affect reliability of supply chains. Given the concerns over national security, the ban on Micron memory devices was executed promptly, which naturally hit the company's revenue.
China's action toward Micron is largely interpreted as a retaliation to the United States' attempt to limit Chinese access to advanced manufacturing technologies. This context of geopolitical maneuvering also includes U.S. efforts to persuade its allies to limit exports of wafer fab equipment to China.
Against this backdrop, the conversation between Wang Wentao and Sanjay Mehrotra reflects a softening of tensions, occurring in the run-up to a planned dialogue between the U.S. President Joe Biden and Chinese President Xi Jinping at the forthcoming Asia-Pacific Economic Cooperation summit in San Francisco, signaling a potential diplomatic warming.
