特朗普（资料图） 特朗普自上任以来，热衷于挥舞"关税大棒"，试图通过加征关税来实现"美国优先"的目标。他不仅对中 国等主要贸易伙伴加征关税，还将关税战的范围扩大到欧盟、日本等盟友。然而，这些关税政策并未如 他所愿，给美国带来经济利益，反而引发了国内外的强烈反对。 在国内，美国的消费者和企业深受关税之苦。关税导致进口商品价格上涨，消费者的生活成本大幅增 加。许多美国企业，尤其是依赖进口原材料的中小企业，面临着生产成本上升、利润下降的困境。据美 国媒体报道，由于关税影响，沃尔玛商场内自哥斯达黎加进口的香蕉价格已经上涨近10%，从中国进口 的汽车安全座椅价格可能要从现在的350美元涨到450美元。这些价格上涨直接影响了消费者的购买能 力，也削弱了美国企业的竞争力。 近期，美国国际贸易法院的一项裁定，让特朗普政府陷入困境。5月28日，该法院裁定特朗普发布的多 项关税令属于越权行为，必须立即停止执行。这一裁决犹如一颗重磅炸弹，在美国国内外引发轩然大 波。 美国国际贸易法院此次裁定，特朗普实施的10%"全球基准关税"、20%"对等关税"，以及针对中国的 20%所谓"芬太尼关税"均违反法律规定。法院认为，特朗普即便宣布"国 ...

Group 1 - The U.S. government has been pursuing deep-sea mining since the 1970s, aiming to expand its influence and control over international seabed resources [1][3] - The Trump administration intensified the focus on "critical minerals," implementing policies to protect the supply chain for key minerals essential for manufacturing and military industries [3][4] - The U.S. has significant deep-sea mineral resources, estimated at over 1 billion tons of polymetallic nodules, which contain essential materials for high-tech products [6][4] Group 2 - The current U.S. administration's push for deep-sea mining reflects a broader strategy to bypass international laws and regulations, aiming to secure critical resource control [9][7] - Environmental experts criticize the U.S. government's actions as reckless and irresponsible, highlighting the potential ecological damage and long recovery times for deep-sea ecosystems [10][12] - The unilateral approach to deep-sea mining raises concerns about the legality and sustainability of such operations, with potential challenges in international recognition and market access for extracted minerals [14][12]

Core Viewpoint - The announcement by President Trump to increase steel and aluminum import tariffs from 25% to 50% is a significant escalation in the "America First" trade policy, aimed at forcing manufacturing to return to the U.S. and impacting global supply chains [2][5]. Trade Reactions - The decision has sparked strong opposition from various countries, including the EU, Canada, and Australia, which expressed concerns over increased uncertainty and costs for consumers and businesses [3]. - Canada and Australia have labeled the move as detrimental to their economies, with Canadian labor leaders calling it a direct attack on workers [3]. Impact on U.S. Market - The increase in tariffs is expected to raise U.S. steel and aluminum import costs significantly, with estimates indicating an additional $220 billion in costs from the previous 25% tariffs and $290 billion for derivative products [4]. - Industries such as automotive, machinery, construction, and appliances will face sharp increases in raw material costs due to the new tariffs [4]. Effects on China’s Steel and Aluminum Industry - As the largest producer of steel and aluminum, China faces severe challenges from the proposed tariffs, which could eliminate remaining trade channels to the U.S. and exacerbate existing issues of domestic demand weakness and overcapacity [5][6]. - The Chinese steel industry is already experiencing low prices and high inventory levels, with many small and independent mills operating at a loss [6]. Challenges for Aluminum Sector - The Chinese aluminum industry, while benefiting from demand in new energy sectors, is also under pressure from high raw material costs and potential losses in U.S. exports due to the tariffs [7]. - The overall economic slowdown and trade tensions may further suppress demand for aluminum products [7]. Strategic Responses - The industry needs to stabilize market expectations and confidence through proactive fiscal policies, particularly in new infrastructure and energy sectors, to absorb excess capacity and support long-term transformation [8]. - China should collaborate with affected trade partners to challenge the U.S. tariffs within the WTO framework, aiming to uphold multilateral trade rules [8]. Long-term Development Strategies - The industry must shift from a focus on volume to quality, targeting high-end materials and advanced manufacturing processes to enhance competitiveness [9]. - Global expansion and local production in target markets are essential strategies to mitigate the impact of tariffs and respond quickly to market demands [9]. Conclusion - The situation remains fluid, and the ultimate outcome of the tariff increase is uncertain, with potential for both significant disruption and opportunities for industry transformation [10].

据和讯网报道，截至2025年4月，美国国债总额超36万亿美元，债务占GDP比重逾120%，利息支出持续快速上升，成为财政支出中增长最快的部分。2025年 美债到期规模与2024年大致持平，但短期国库券到期滚续压力显著高于以往，期限结构进一步偏短。尽管财政部发债节奏总体稳定、违约风险依然极低，但 当前美债面临的核心挑战转向需求端承接能力下降与融资成本上升，供需矛盾加剧使美债收益率下行空间受限。 这一外交动向引发全球瞩目，不仅标志着特朗普执政以来首次踏上非洲大陆，更预示着美非关系可能迎来历史性转折。自2017年入主白宫以来，特朗普政府 的"美国优先"政策使其对非关注度相对有限。此前，特朗普曾通过多种渠道放言，他不会出席在非洲召开的G20峰会。此次他又高调宣布出席G20峰会，被 视为其全球战略调整的重要信号。国际观察家指出，在中国"一带一路"倡议持续深化、俄罗斯重返非洲的背景下，特朗普此行意在重振美国在非洲大陆的经 济与地缘政治影响力。 特朗普需要改革，但更需要稳定霸权基础，至少在动刀改造美债之前，美债不能崩，而想要实现这一目标，就或多或少有求于中国。一方面，中国是美债第 二大债权国，短期内的增持减持并没有太大意义 ...

据报道，在国际局势风云变幻的当下，特朗普的一系列举措正深刻影响着世界格局。当地时间 5 月 23 日，特朗普在社交媒体上抛出重磅消息，建议自 2025 年 6 月 1 日起，对欧盟直接征收 50% 的关税。这 一建议如同一颗投入平静湖面的巨石，瞬间激起千层浪，让本就复杂的美欧关系愈发紧张。 此外，特朗普还试图在贸易问题上 "连欧抗中"。一份流传给爱尔兰政府部长和高级官员的美方泄密文 件显示，美国试图通过关税与谈判双管齐下，迫使欧盟 27 国在 "美国或中国" 之间作出选择，并将此要 求与削减新关税直接捆绑。然而，欧洲根本无法接受这种强 迫选边的做法，毕竟中国已成为欧盟第二大贸易伙伴，欧洲在中国市场有着巨大的经济利益。 美国与欧盟之间的贸易逆差一直是特朗普政府关注的焦点。据美国贸易代表办公室数据显示，2024 年，美国对欧盟货物贸易逆差高达 2356 亿美元，相较于 2023 年增加了 12.9%。欧盟委员会数据也表 明，2023 年欧盟对美国实现 1570 亿欧元的货物贸易顺差，尽管存在 1090 亿欧元的服务贸易逆差，但 整体仍有 480 亿欧元（约合 542 亿美元）的贸易顺差。如此明显的贸易不平衡，使得 ...

美国民众（资料图） 据大皖新闻报道，美国12个州组成联盟于4月23日共同起诉特朗普政府，指控其关税政策违法。美国国际贸易法院开庭审理此案。当地时间5月21日，在美国 纽约市曼哈顿下城的美国国际贸易法院，三名法官对于12州诉特朗普政府关税违法一案进行了庭审。抗辩双方的都进行了陈述并回答了法官的质疑。其中， 代表原告方面进行陈述的是来自于俄勒冈州总检察长马歇尔。 特朗普（资料图） 这一裁决不仅标志着特朗普的"关税战"首次遭遇联邦法院的实质性否决，宣告了他关税战的彻底战败，同时也打破了他"我就是国王"的幻想。然而，面对司 法系统的明确警告，特朗普并未退缩，反而立刻上诉，并誓言继续推进"美国优先"的极端政策。首先需要明确的是，针对这一裁决，特朗普团队是极为愤怒 的。被称为特朗普"新国师"的白宫副幕僚长史蒂芬·米勒，在社交媒体上怒斥："这是一次司法政变，已经失控。"而发言人库什·德赛更是语出惊人："非民选 法官无权决定如何应对国家紧急状态。" 虽然此次诉讼主体是非盈利、无党派诉讼机构自由正义中心代表五家受关税影响的美国小企业提起，如果围绕法律战要继续打下去，将会是一个漫长的官 司，中美90天关税缓冲期打完之后，或许都没 ...

Core Viewpoint - The withdrawal of Jared Isaacman’s nomination as NASA Administrator by Trump indicates a shift towards a more politically aligned leadership, potentially impacting NASA's strategic direction and commercial partnerships, particularly with SpaceX [2][10][31]. Group 1: Political Dynamics - Trump announced the withdrawal of Isaacman's nomination due to his past donations to prominent Democrats, reflecting a preference for candidates with a "pure" political stance [2][10]. - The decision to withdraw the nomination may lead to a leadership vacuum at NASA, creating uncertainty in its long-term strategic planning [3][10]. - Trump's intention to nominate someone aligned with the "America First" agenda suggests a potential shift away from the commercialization and privatization trends that Isaacman represented [9][10]. Group 2: Impact on NASA and SpaceX - Isaacman, a billionaire and private astronaut, was seen as a candidate who could enhance NASA's efficiency through commercialization, which is now uncertain following the withdrawal [3][9]. - The potential new nominee, Steven Kwast, a retired Air Force general, indicates a possible return to a more traditional, government-focused approach to NASA's leadership [9][10]. - The cancellation of Isaacman's nomination raises questions about the future of NASA's lunar and Mars exploration strategies, which had been leaning towards commercial partnerships [9][10]. Group 3: Financial Implications - SpaceX has significantly benefited from NASA's commercial contracts, with over $84 billion invested in commercial crew programs, of which SpaceX accounts for about 30% [21]. - The political dynamics surrounding NASA's leadership could affect SpaceX's future contracts and operational strategies, particularly in light of the recent budget proposals that may cut NASA's funding [10][21]. - SpaceX's revenue is projected to grow significantly, with estimates suggesting a rise from $8.7 billion in 2023 to $13.1 billion in 2024, driven largely by its Starlink business [19].
