Titanium Media App learned that as of 15 pm on October 11, the chip semiconductor sectors in Shanghai and Shenzhen continued to weaken, while chip-related stocks in the United States, Japan, South Korea and Hong Kong, China saw a sharp drop. The main reason is that the US Department of Commerce recently announced new export controls on chips in China, and the poor financial performance of semiconductor companies has triggered market sell-offs.

According to Global Times , the United States issued a series of new regulations on October 7, prohibiting the sale of certain chips made using US equipment to China. In addition, the U.S. government has included 31 Chinese companies, research institutions and other groups on the so-called "unverified list", limiting their ability to obtain certain regulated U.S. semiconductor technology. This policy highlights how tensions between Washington and Beijing have changed the $550 billion global semiconductor industry.
Many institutions believe that this will help domestic substitution. China Merchants Securities Electronics Team released a research report on October 9, pointing out that this move in the United States will strengthen the logic of domestic substitution, especially the domestic companies' production expansion plans for 2023 are clear, and it is expected that domestic equipment manufacturers will perform significantly better than overseas manufacturers in 2023. Chief analyst at SemiAnalysis said that some Chinese AI chip design companies and TSMC may face some restrictions.
In response, Chinese Foreign Ministry spokesperson Mao Ning responded on October 8 that the United States abused export control measures to maliciously block and suppress Chinese companies in order to maintain technological hegemony. This practice deviates from the principle of fair competition and violates international economic and trade rules, which not only harms the legitimate rights and interests of Chinese companies, but also affects the rights and interests of American companies.
Mao Ning stressed that this approach hinders international scientific and technological exchanges and economic and trade cooperation, and will have an impact on the stability of the global industrial chain and supply chain and the recovery of the world economy. The US politicization, instrumentalization and weaponization of science and technology and economic and trade issues cannot stop China's development, but will only block itself and backfire itself.
