美国最高法院的裁决并不意味着该国总统特朗普处心积虑构建的关税壁垒就此"击溃"，他还可能凭借手 头的多种工具让大规模关税卷土重来。 据央视新闻，当地时间20日，美国最高法院裁定，特朗普政府依据《国际紧急经济权力法》（IEEPA） 实施的相关大规模关税措施缺乏明确法律授权。这一裁决推翻了特朗普第二个总统任期内实施的大部分 关税措施，但裁决并未终结关税政策本身。 虽然这一裁决动摇了特朗普的核心经济政策，但特朗普可以重新启用他在第一任期内使用的关税权力， 还可以动用其他权力，包括上世纪30年代美国大萧条时期问世的一项法律赋权。 华尔街见闻综合各方分析发现，特朗普拥有至少五种替代IEEPA的法律工具重建关税体系，不过，这些 工具相比IEEPA均附带更多的限制条件。 据新华社报道，2018年3月，特朗普签署总统备忘录，依据"301调查"结果，计划对从中国进口的商品大 规模征收关税，并限制中国企业对美投资并购。同年7月和8月，美国分两批对从中国进口的500亿美元 商品加征25%关税。中方依法对美产品采取了同等力度、同等规模的对等措施。2018年9月，美国对 2000亿美元中国输美产品加征10%的关税。作为反制，中方对价值6 ...
