不降反增，英澳反对美新关税措施

Core Viewpoint - The U.S. Supreme Court ruled that the International Emergency Economic Powers Act does not authorize the President to impose large-scale tariffs, leading President Trump to invoke other legal provisions to impose a 15% tariff on imports, raising concerns from the UK and Australia about increased export costs and weakened competitiveness [1][2]. Group 1: Impact on Trade Relations - The new tariffs will increase the tariff rate on UK goods exported to the U.S. from 10% to 15%, excluding items covered by the trade agreement reached last year [1]. - Australian products, which previously benefited from a free trade agreement eliminating most tariffs, may now face higher tariffs due to the new U.S. measures [1][2]. Group 2: Reactions from Officials - UK Chamber of Commerce's trade policy director expressed disappointment, estimating that the increased tariffs will raise the cost of UK exports to the U.S. by £2 to £3 billion (approximately $2.7 to $4.1 billion) [1]. - Australian officials, including the Trade and Tourism Minister, expressed disappointment and urged the U.S. to abandon the new tariffs, emphasizing the need for a rules-based trading order [2]. Group 3: Economic Implications - Analysts suggest that the uncertainty surrounding U.S. tariff policies could have lasting impacts on international trade and add downward pressure to global economic recovery amid ongoing supply chain disruptions and geopolitical tensions [2].
