特朗普被打了措手不及，白宫传来风声，美国这回彻底“输了”？

Core Viewpoint - The U.S. International Trade Court's ruling against the Trump administration's tariffs under the International Emergency Economic Powers Act has significant implications for U.S. trade policy and global trade dynamics [1][4][6]. Summary by Sections Trump's Tariff Policy - In February, the Trump administration imposed tariffs on imports from Canada, Mexico, and China, citing the need to protect domestic industries and adjust trade balances [1][3]. - The tariffs included a 10% baseline tariff on all imports starting April 5, with higher tariffs for countries with significant trade deficits, set to begin on April 9 [1][3]. Impact of Tariffs - Despite a 12% decrease in Chinese exports to the U.S. from 2018 to 2024, the U.S. trade deficit with China increased by 11% to $361 billion in 2024 compared to 2017 [3]. - The International Monetary Fund (IMF) revised its global economic growth forecast down from 3.3% to 2.8% for 2025, reflecting the negative impact of the trade war [3]. Court Ruling - The U.S. International Trade Court ruled that the International Emergency Economic Powers Act does not authorize the president to impose global tariffs, leading to the permanent prohibition of the tariffs [4][6]. - The ruling was initiated by lawsuits from five small businesses and twelve states, arguing that the tariffs were enacted without congressional approval [4][6]. Implications for the Trump Administration - The ruling represents a significant setback for the Trump administration, which relied on tariffs as a key tool for negotiating trade deals and promoting its "America First" policy [6]. - The White House announced plans to appeal the ruling, questioning the legitimacy of judicial intervention in national emergency policies [6]. Broader Political and Global Trade Impact - The ruling intensifies the conflict between executive and judicial powers in the U.S., as tariff imposition is constitutionally a congressional power [8]. - While the ruling may create short-term uncertainty in U.S. trade policy, it could potentially stabilize global trade in the long run, depending on the outcome of the appeal [8].
