Core Viewpoint - The article discusses the evolving U.S. policy on semiconductor exports to China, highlighting two key statements made by U.S. Commerce Secretary Gina Raimondo that reflect a shift from a comprehensive blockade to a more targeted control strategy [1][3][5]. Group 1: First Statement Context - The first statement occurred between April and August 2025, during which the Trump administration continued its comprehensive blockade on semiconductor exports to China. Raimondo stated that the U.S. would not sell high-quality products to China, even limiting third-tier products, with the core aim of making Chinese companies dependent on U.S. technology [1]. - This statement was made shortly after the U.S. government suspended NVIDIA's export license for the H20 chip to China, indicating a continuation of the "one-size-fits-all" tech blockade strategy aimed at stifling China's industrial upgrade [1]. Group 2: Second Statement Context - The second statement was made in mid-August 2025, after the Trump administration approved NVIDIA's export license for the H20 chip. Raimondo adjusted her stance, suggesting that the U.S. would sell products to China that were "just enough" for their needs, aiming to make developers dependent on U.S. technology stacks [3]. - This change in policy was marked by NVIDIA and AMD agreeing to pay 15% of their sales revenue from China to the U.S. government in exchange for the restoration of export licenses, indicating a shift from "comprehensive blockade" to "precise control" [3]. Group 3: Implications of the Statements - Both statements were made through CNBC, showcasing the U.S. government's use of mainstream financial media as a tool for public discourse. The ongoing blockade has led to significant risks for companies like NVIDIA, which face potential market share losses in China [5]. - The performance breakthroughs of domestic Chinese chips, such as those from Huawei and Cambrian, have rendered the blockade increasingly ineffective, forcing the U.S. government to reconsider its strategy [5]. Group 4: Future Strategies - To achieve the goal of providing products that are "just enough" without exceeding limitations, the U.S. is likely to accelerate the implementation of a "chip governance mechanism." Reports suggest that NVIDIA's chips may soon include tracking and remote shutdown features, potentially enforcing geographical restrictions on their use [5][6]. - The U.S. may also strengthen the binding effect of the CUDA system, which is relied upon by over 4 million developers globally. This could involve limiting access to high-level API interfaces and delaying critical updates, creating a dependency trap for Chinese companies in AI model training [6]. Group 5: Speculative Measures - There is speculation that China may require all imported chips to undergo "backdoor clearance" certification, enforcing mandatory technical reviews on critical components. Companies that refuse to comply could be placed on an "unreliable entity list," creating a regulatory deterrent [7].
