中美新一轮谈判在即，华盛顿提前亮牌，这次还牵扯到俄罗斯和伊朗

Group 1 - U.S. Treasury Secretary Mnuchin claims that U.S.-China trade negotiations are progressing smoothly, but the Trump administration prioritizes "quality" over urgency in signing an agreement [1] - Mnuchin threatens to include China's purchases of Russian and Iranian oil in the negotiation agenda, stating that China is a major buyer of sanctioned Iranian and Russian oil [1] - The U.S. strategy aims to pressure China by leveraging its significant oil imports from Russia, which account for 19.6% of China's total oil imports, with 84% of Russian oil exports going to China and India in 2024 [1] Group 2 - The Trump administration's approach appears contradictory, as it seeks to use tariffs to compel China to abandon Iranian and Russian oil while simultaneously expressing a desire for China to purchase more U.S. oil [2] - This inconsistency highlights Washington's strategic confusion, as it attempts to apply economic pressure while also coveting China's market purchasing power [2] - Mnuchin's introduction of new conditions for negotiations reflects an effort to add leverage, but tying energy security to trade negotiations is unlikely to succeed and reveals U.S. anxiety over its inability to solely rely on economic measures against China and Russia [2]
