美国财长急催G7！对买俄石油国家加关税，称能打破俄乌问题僵局？

Core Viewpoint - The U.S. Treasury Secretary has called on G7 nations to support the proposal of imposing tariffs on countries purchasing Russian oil, emphasizing its significance in addressing the Ukraine issue [1][3]. Group 1: U.S. Proposal and Intent - The U.S. aims to impose tariffs on countries buying Russian oil to reduce Russia's energy export revenue, which is crucial for funding its military operations in Ukraine [3][4]. - The proposal is seen as a strategic move to decrease international demand for Russian oil and weaken Russia's financial resources, thereby enhancing Ukraine's negotiating position [3][4]. Group 2: Controversies and Challenges - The proposal faces opposition from countries heavily reliant on Russian oil, as it could increase their energy import costs and exacerbate domestic inflation [4][5]. - There are internal disagreements within the G7 regarding the extent and nature of sanctions against Russia, with some members preferring targeted sanctions rather than imposing pressure on third-party oil purchasers [4][5]. - The effectiveness of the proposed tariffs is uncertain, as previous sanctions have been mitigated by Russia's adjustments in export strategies and partnerships with non-Western countries [4][5].
