专题：美最高法院裁定特朗普全球关税违法 特朗普回应裁决是"耻辱" 在最高法院推翻了美国总统特朗普去年实施的大部分关税政策后，特朗普表示，他将签署一项命令，征 收10%的全球基准关税，此外还将启动一系列调查，为征收更多进口关税做准备。 "最高法院并没有废除关税，他们只是驳回动用《国际紧急经济权力法》（IEEPA）征收关税，"特朗普 在白宫告诉记者。"现在我将转向一个不同的方向，这可能是我一开始就该采取的方向。" 特朗普表示，他将根据《1974年贸易法》第122条征收基准关税，该条款赋予总统单方面征收关税的能 力。但这一法条限制了潜在的关税征收范围，且规定关税持续时间不得超过150天。特朗普预计，10% 的新基准税率将在三天后正式生效。 特朗普还表示，将根据"第301条"和"第232条"启动新的进口调查。他建议，这些调查可以在10%的基准 关税实施期间进行，并最终取代前者，不过他拒绝排除寻求延长（或重新引用）"第122条"征税的可能 性。特朗普表示，他在考虑对外国汽车征收15%到30%不等的关税。 在特朗普宣布10%征税计划后，债券收益率收窄早前涨幅，美股扩大涨势。 特朗普 特朗普在开场白中对最高法院发起猛烈抨击 ...

Core Viewpoint - The U.S. Trade Representative, Jamison Greer, has made controversial statements urging Canada and Mexico not to become export centers for countries like China, Vietnam, and Indonesia, indicating a desire for U.S. control over their trade policies [1][5]. Group 1: U.S.-Canada-Mexico Trade Relations - Greer criticized Canada and Mexico for their tariffs on foreign cars, suggesting that the USMCA (United States-Mexico-Canada Agreement) has issues, yet acknowledged that both countries are significant export markets for the U.S. [3][5]. - There are indications that Trump may consider withdrawing from the USMCA, despite its stipulations requiring member countries to maintain the agreement until 2036 [5][9]. - Greer proposed the idea of negotiating separately with Canada and Mexico, arguing that their economic relationships with the U.S. are distinct, which contradicts the original intent of the trilateral agreement [7]. Group 2: Global Trade Dynamics - Greer’s comments reflect a unilateral approach to trade, attempting to dictate terms to Canada and Mexico while downplaying their economic independence and needs [12]. - The interconnectedness of global supply chains makes it impractical for the U.S. to enforce a complete decoupling from China, as this could adversely affect American businesses as well [3][12]. - Canada and Mexico are actively seeking to diversify their trade relationships, as evidenced by Mexico's efforts to upgrade its free trade agreement with the EU to reduce reliance on the U.S. market [10][12].
