对华半导体遏制再升级？美议员呼吁全面禁运

Core Viewpoint - A bipartisan group of U.S. lawmakers is urging the Trump administration to impose a comprehensive ban on the export of semiconductor manufacturing equipment to China, citing the ineffectiveness of current targeted trade restrictions [2]. Group 1: Legislative Actions and Recommendations - The lawmakers argue that the current export control system has significant loopholes, as it only targets specific entities within China rather than implementing a nationwide ban [2]. - They emphasize the need for the U.S. government and its allies to enforce nationwide restrictions on critical semiconductor manufacturing equipment and components that China cannot currently produce domestically [2]. - The group highlights the importance of addressing the supply chain's vulnerabilities, particularly concerning equipment produced by Dutch companies, which has reportedly doubled from 2022 to 2023 and is expected to double again from 2023 to 2024 [3]. Group 2: Urgency and Strategic Concerns - The lawmakers express urgency in their recommendations, warning that if China continues to develop its own chip manufacturing technology without restrictions, it could render U.S. and allied export controls ineffective [3]. - They also call for strict actions against companies that provide after-sales maintenance services for existing controlled equipment in China, indicating a broader strategy to limit China's technological advancements [3].
