近日，美国宣布将对与伊朗有贸易往来的国家或企业加征25%的关税，作为其加强对伊朗经济制裁的一部分。此举旨在进一步孤立伊朗经济，迫使其在核计划和地区政策上作出让步。根据美方声明，任何被认定与伊朗存在‘重大贸易关系’的第三方国家或实体，若未配合美国对伊制裁措施，将面临额外关税惩罚。这一政策延续了美国近年来对伊朗采取的‘极限施压’策略。自2018年美国单方面退出伊核协议（JCPOA）以来，已多次扩大对伊制裁范围，并试图通过次级制裁（secondary sanctions）阻止其他国家与伊朗开展正常经贸合作。此次25%的关税措施，主要针对能源、金属、航运等关键领域，可能影响包括中国、印度、土耳其等曾与伊朗保持贸易关系的国家。分析人士指出，该举措可能加剧全球供应链紧张，并引发贸易伙伴的反制。同时，也有观点认为，过度依赖单边制裁难以实现长期外交目标，反而可能推动受制裁国寻求替代性经济合作机制。目前，国际社会对美国此类单边行动反应不一，部分国家呼吁通过多边对话解决伊核问题。
Recently, the United States announced it would impose an additional 25% tariff on countries or companies trading with Iran, as part of its intensified economic sanctions against Tehran. The move aims to further isolate Iran economically and pressure it into concessions on its nuclear program and regional policies. According to the U.S. statement, any third-party nation or entity deemed to have ‘significant trade ties’ with Iran and failing to comply with U.S. sanctions could face these punitive tariffs.This policy continues Washington’s strategy of ‘maximum pressure’ on Iran. Since unilaterally withdrawing from the Joint Comprehensive Plan of Action (JCPOA) in 2018, the U.S. has repeatedly expanded sanctions and used secondary sanctions to deter other nations from engaging in normal trade with Iran. The new 25% tariff primarily targets key sectors such as energy, metals, and shipping, potentially affecting countries like China, India, and Turkey that have maintained trade relations with Iran.Analysts warn the measure could exacerbate global supply chain disruptions and provoke retaliatory actions from trade partners. Others argue that overreliance on unilateral sanctions may fail to achieve long-term diplomatic goals and instead push targeted countries toward alternative economic alliances. The international response remains divided, with some nations urging multilateral dialogue to resolve the Iran nuclear issue.
