7月21日，美国财政部长贝森特在接受CNBC采访时放话：中美下一轮会谈的核心议题，将从传统贸易争端转向中国从俄罗斯与伊朗购买石油的行为。他直 言，北京是"被制裁的伊朗石油与俄罗斯石油的主要买家"，并暗示美国可能对相关国家征收最高500%的"次级关税"。这一表态，标志着美国对华博弈的战 场正式转移——当关税大棒在新能源、芯片等领域收效甚微后，华盛顿试图以能源安全为切口，开辟中美较量的新前线。 2月10日起，中国对美国原油和液化天然气分别加征94%和99%关税，直接导致美国对华能源出口断崖式下跌。上半年，美国在中国原油进口来源国排名中 暴跌至第15位，3月后几乎再无美国油轮靠岸。贝森特的发言，实质是将能源与地缘政治捆绑：以"次级制裁"威胁切断中俄、中伊能源纽带。这一招直指中 国能源生命线——2025年中俄贸易额预计突破3000亿美元，能源占比超40%；中国进口的俄罗斯原油占其出口总量的47%，更通过"西伯利亚力量"管道接收 天然气，年增速达20%。 这场能源博弈的终局，不会由关税或制裁决定，而取决于谁能掌控"能源自主权"：中国以技术升级和多元布局锻造盾牌，美国则因战略透支与盟友离心渐显 疲态。当石油管道成为新战场 ...
