美国撤回AI芯片出口新规，全球算力“守门人”计划搁浅

Core Viewpoint - The U.S. Department of Commerce has officially withdrawn the controversial "AI Action Plan Implementation" rule, which aimed to shift AI chip export controls from "country-specific restrictions" to a "global licensing system," marking a significant setback for the Trump administration's efforts to reshape the global AI chip supply chain [1]. Group 1: Policy Shift - The rule was initially posted on February 26 and was in "pending review" status, but was formally withdrawn on March 13, just a day after the review deadline [2]. - The withdrawal is seen as part of a broader internal policy adjustment within the Trump administration, which had previously promised a "simplified" set of rules to replace the complex export framework established by the Biden administration [2]. Group 2: Proposed Global Gatekeeper Mechanism - The withdrawn rule aimed to position the U.S. as the "ultimate gatekeeper" of global AI computing power, expanding export controls to all countries rather than just around 40 [3]. - The proposed "tiered approval" mechanism included different requirements based on the scale of deployment: - Small deployments (<1,000 chips) would have a simplified review process and potential exemptions [4]. - Medium to large clusters (>1,000 chips) would require pre-approval and could face commercial model disclosures or on-site inspections [5]. - Large-scale deployments (>200,000 chips) would necessitate government involvement from the buyer's country, with approvals granted only to allies making "reciprocal investments" in the U.S. AI sector [6]. Group 3: Internal Conflicts and Market Reactions - Analysts suggest the withdrawal may stem from significant internal divisions within the U.S. government, particularly between the White House and the Department of Commerce [8]. - Pressure from the industry, particularly from major chip companies like NVIDIA and AMD, contributed to the withdrawal, as their stock prices fell following the announcement of the proposed rule [9]. - The inclusion of close allies in a strict approval system could strain diplomatic relations, conflicting with the Trump administration's "America First" strategy [10]. Group 4: Impact on the Global AI Industry - The withdrawal alleviates immediate tensions in the global AI industry, allowing it to return to a more familiar regulatory framework under the Biden administration [11]. - However, uncertainties remain as the Trump administration continues to seek a new export control framework that balances national security and commercial interests [11]. - For China, the withdrawal does not signify a relaxation of restrictions, as it remains on the "blacklist," and previous approvals for exports of advanced chips to China are still on hold [11].
