涉半导体豁免，美国放风取消

Group 1 - The U.S. Department of Commerce is considering revoking exemptions that allow major semiconductor manufacturers like TSMC and Samsung to use U.S. technology in their factories in mainland China, raising concerns in Taiwan and South Korea [1][3] - Currently, TSMC, Samsung, and SK Hynix enjoy full exemptions, allowing them to ship U.S. chip manufacturing equipment to their factories in China without needing individual licenses [1][3] - The proposed revocation is seen as part of the U.S. government's efforts to prevent critical technology from flowing to China, although it has not yet received support from other government departments like the Department of Defense [3][4] Group 2 - If implemented, the new measures could complicate operations for global chip manufacturers in mainland China and may strain U.S. relations with Taiwan and South Korea, which have made significant investments in the U.S. [3][4] - Samsung's factories in Xi'an and Suzhou are particularly vulnerable, with the Xi'an facility accounting for approximately 40% of Samsung's global NAND flash memory production [3][4] - The potential revocation of exemptions could lead to a shift in procurement strategies for South Korean companies, possibly forcing them to consider alternatives from Japan and Europe [3][4] Group 3 - The South Korean government is urged to actively coordinate efforts to minimize the impact on national strategic industries amid increasing tech competition between the U.S. and China [4] - Taiwanese media suggest that if the U.S. proceeds with the revocation, it could inadvertently benefit China's semiconductor equipment industry [4] - The cancellation of exemptions may force companies to adopt a case-by-case application system, significantly affecting the global chip supply chain [4]
