On September 14th local time, China and the United States held talks on economic and trade issues in Madrid, Spain. The discussion topics include unilateral tariff measures by the United States, abuse of export controls, and TikTok. All parties hope that this meeting can achieve positive results. Just before the talks, on the 12th local time, the US Department of Commerce announced the inclusion of multiple Chinese entities in the so-called export control "entity list". The Financial Times reported that this is another example of China's opposition to US export controls. On the evening of the 13th, the spokesperson of the Chinese Ministry of Commerce responded to reporters' questions by stating that the US Department of Commerce has generalized national security and abused export controls, imposing sanctions on multiple Chinese entities in the fields of semiconductors, biotechnology, aerospace, and commercial logistics. Starting from September 14th, China and the United States will hold economic and trade talks in Spain. What is the intention of the United States to impose sanctions on Chinese companies at this time? "On the same day, the Chinese Ministry of Commerce announced two investigations into the United States: launching an anti discrimination investigation into measures taken by the United States in the integrated circuit field against China, and launching an anti-dumping investigation into imported analog chips originating from the United States. Experts told Global Times reporters that the United States is banning the export of high-end chips to China while dumping related analog chips, adopting differentiated strategies to suppress China's technology.
