China has banned Micron Technology, a leading US semiconductor company, as part of an escalating trade tensions between the two nations. The Chinese government has instructed owners of crucial national infrastructure to avoid purchasing goods from US chipmaker Micron Technology. 

The Cyberspace Administration of China (CAC) said in a statement: 'The review found that Micron's products have serious network security risks, which pose significant security risks to China's critical information infrastructure supply chain, affecting China's national security.'

The move comes after the United States blacklisted several Chinese technology companies, citing concerns over national security. China's ban on Micron Technology, which is a major producer of memory chips used in smartphones and other electronic devices, is expected to have significant repercussions for the global tech industry. The ban threatens to disrupt the supply chain and could lead to shortages of memory chips in the market. Micron Technology's stock prices have already been affected by the news, and the company is evaluating the potential impact on its business. The situation highlights the vulnerability of companies operating in the semiconductor industry, as they navigate geopolitical challenges and the impact of trade restrictions on their operations.
