On December 23, USA time, the Office of the United States Trade Representative announced the initiation of a 301 investigation into China's chip industry-related policies. China expresses strong dissatisfaction and firmly opposes this. The USA's 301 investigation clearly has unilateral and protectionist characteristics. Previously, the USA's 301 tariffs against China were ruled by the World Trade Organization to violate trade rules, facing opposition from many WTO members, and China has repeatedly lodged stern representations to the USA. The USA's initiation of a new 301 investigation into China's chip industry-related policies, driven by the need to suppress China and domestic political requirements, will disrupt and distort the Global chip Industry Chain and supply chain, and will also harm the interests of USA enterprises and consumers, which is a repeated mistake. The USA provides huge subsidies to its own chip industry through the "CHIPS and Science Act", with USA companies holding nearly half of the global chip market share, yet it accuses China of so-called "non-market practices" and exaggerates the threat of China's industry, which is clearly contradictory and untenable. The recent report from the USA Department of Commerce on mature process chips shows that Chinese chips account for only 1.3% of the USA market share. Exports of Chinese chips to the USA are far lower than imports from the USA. China urges the USA to respect facts and multilateral rules and immediately cease these erroneous practices. China will closely monitor the progress of the investigation and will take all necessary measures to firmly safeguard its own rights and interests.
