特朗普政府关税B计划曝光，转折点出现了吗？

Core Viewpoint - The article discusses the potential legal challenges facing the Trump administration's tariff policies, particularly in light of a recent court ruling that deemed most of these tariffs illegal, and the administration's plans to respond to these challenges through alternative measures [1]. Group 1: Legal Context - On August 29, the U.S. Court of Appeals ruled that most of the Trump administration's tariff measures are illegal, which undermines the administration's ability to use tariffs as a key economic policy tool [1]. - The appeals court has allowed these tariffs to remain in place until October 14, giving the Trump administration time to appeal to the Supreme Court [1]. Group 2: Government Response - U.S. Treasury Secretary Mnuchin indicated that the government has a backup plan in case the Supreme Court rules against the administration's tariff policies [1]. - Mnuchin is preparing a legal summary for the Attorney General that emphasizes the urgency of addressing long-standing trade imbalances and preventing fentanyl from entering the U.S. [1]. Group 3: Expert Opinions - Experts interviewed by the media expressed that Mnuchin's statements were not surprising, noting that the frequent use of Section 232 investigations suggests the Trump administration is exploring alternative tariff strategies beyond the so-called "reciprocal tariffs" [1].
