据智通财经报道，近期，美国财政部公布的数据显示，2025年3月，美债前三大海外债主中，日本、英国增持美国国债，中国减持。中国由美 国第二大债主变为第三大债主，英国变为第二大债主。3月正值本轮美债市场动荡前夕。 特朗普（资料图） 根据美国财政部本周五公布的数据，截止今年3月底，中国持有的美债降到了7654亿美元。这波减持后，中国美债的持仓规模被英国超越，日 本、英国和中国分别为美国的前三大债主。这次关税战爆发后，市场大规模抛售美债，导致美债收益飙升，美国联邦政府债务游走在爆雷的边 缘，估计惊出了特朗普一身冷汗。尽管在关税战期间，没有消息显示中国也减持了美债，但中国持有这么多美债，随便抛售一点，都可能搅动 美债市场，杀伤美国的金融体系。 毫无疑问，虽然现在中国降为美国的第三大债主，但7600多亿美元的美债持仓，依旧称得上高悬在特朗普头上的"达摩克利斯之剑"。 美国有线电视新闻网（CNN）报道称，特朗普到访的三个能源富国，每个国家都对美国有着长长的诉求清单。尽管这些国家豪掷重金，但美 国并未实现所有诉求。沙特希望与美国达成正式安全协议，显然未能如愿。彭博经济中东事务负责人迪娜・埃斯凡迪亚里（Dina Esfandi ...

石破茂（资料图） 实际上，从日本一开始与美国接触，日本的态度就表现得不积极。作为首个与美国就贸易问题进行会谈的国家，它一直都被全世界关注着，而且它也在美国 重点关照的名单中，此前很多猜测认为日本会最先与美国达成协议。不过，在日美接触的过程中，美国提出的要求十分离谱。有不少消息传出，美国试图与 日本就汇率问题进行谈判，并放在贸易问题中作为条件。虽然这一消息在后续被美国否认，但美国后来又向日本提出，在亚洲开发银行里，停止对中国进行 贷款。 据报道，日本首相石破茂5月12日在国会明确表态，日方不会接受任何不包含汽车关税条款的日美贸易临时协议。据彭博社报道，当被问及"美国要求日方签 署不含汽车关税条款的临时协议的可能性"时，石破茂强调："我们始终坚持汽车关税必须作为谈判核心议题。"日本经济再生担当大臣赤泽亮正同步表明立 场，称日方将继续要求美方撤销全部关税措施。据日本放送协会披露，日方已向美方提出汽车产业一揽子方案，包括扩大在美汽车产业投资规模、强化船舶 制造领域合作等具体措施。但石破茂同时重申谈判原则：日本不会为了保护汽车而牺牲其农业市场。 其实日本从一开始对美态度就比较强硬，多次公开对美关税政策说"不"，明确表示 ...
