新关税公布不到24小时，印度带头“跳船”，特朗普再遭拖延战术

Core Viewpoint - The U.S. Supreme Court's ruling against Trump's tariff policies has disrupted his trade agenda, leading to India's decision to postpone trade negotiations, highlighting the diminishing effectiveness of U.S. unilateral tariffs [1][3]. Group 1: Supreme Court Ruling and Immediate Impact - On February 20, the U.S. Supreme Court ruled that several of Trump's tariff policies lacked legal authorization and were unconstitutional, undermining the core basis of his trade war [1]. - Following the ruling, Trump announced a new 10% tariff on global imports, which was quickly raised to 15%, while he promised to finalize a legal tariff framework within 150 days [1]. Group 2: India's Response and Strategic Considerations - India officially confirmed on February 22 that it would indefinitely postpone its planned trade negotiations with the U.S., citing the uncertainty created by the Supreme Court's ruling on U.S. tariff policies [1]. - The postponement reflects India's reassessment of the U.S.-India trade agreement, which had previously included significant concessions from India, such as reducing tariffs from 50% to 18% and halting Russian oil purchases [1][3]. Group 3: Broader Implications for Global Trade - India's decision to delay negotiations may signal a shift among global trade partners regarding U.S. policies, potentially prompting other countries to reassess their commitments to trade agreements with the U.S. [5]. - The U.S. Trade Representative has attempted to reassure partners by stating that punitive tariffs can be legally reinstated and that existing trade agreements remain valid, but this reassurance may lack credibility given the legal uncertainties [5]. - The Supreme Court's ruling indicates that Trump's approach to implementing tariffs without Congressional approval is now significantly hindered, suggesting that more countries may exploit the vulnerabilities in U.S. trade policy to negotiate better terms [5].
