Group 1 - Venezuela has become a burden for the United States, which has gained access to its oil but faces challenges in selling and refining it [2] - The U.S. is now the sole distributor of Venezuelan oil, but its refineries lack the capacity to process the increased supply, leading to logistical issues [2] - In January, Venezuelan oil exports to the U.S. reached 284,000 barrels per day, a nearly threefold increase, but Chevron's refinery can only handle 150,000 barrels per day [2] Group 2 - China, once the largest buyer of Venezuelan oil, now accounts for only 0.07% of total imports, despite having the technology to process heavy oil [3] - Venezuelan oil production has plummeted from over 3 million barrels per day at its peak to less than 1 million barrels per day currently, with the Orinoco heavy oil belt producing only 410,000 barrels per day [3] - The cost of refining Venezuelan oil is high, ranging from $23 to $30 per barrel, and significant investment is needed to repair aging facilities, deterring international capital [3]

这场外交大翻脸的背后，实际上是新总统帕斯的政治算计。帕斯是一位出身中右翼政党的领导人，早年 曾在美国接受过经济学教育，思想理念与之前的左翼政府截然不同。上任当天，他宣布恢复与美国断交 17年的大使级外交关系，这本身就显示了他亲美的政治取向。对于帕斯政府来说，美国是能够帮助玻利 维亚摆脱困境的救世主。他们认为，只要紧紧依靠美国，就能迅速获得外资涌入、美元援助，从而解决 国内的高通胀和外汇短缺问题。在他们的设想中，依附美国不仅能填补短期的资金空缺，还能借助美国 的名气，把玻利维亚的锂矿资源炒热并实现经济价值。所以，新政府愿意通过牺牲与中国的合作来作为 向美国示好的投名状，翻脸速度快得令人吃惊。美国方面自然也乐见其成。近年来，美国一直渴望重新 掌控拉丁美洲，而玻利维亚的锂矿资源，作为新能源时代的白色黄金，对美国构建清洁能源产业链至关 重要。在玻利维亚新政府急需援助的情况下，美国自然会提出合作的橄榄枝。玻利维亚渴望获得美国的 资金和技术承诺，而美国则盯着玻利维亚的锂矿资源，希望能借此巩固自己的国际地位。双方的需求不 谋而合，促使玻利维亚政府做出了这一外交转向。 但现实真如新政府所设想的吗？目前的玻利维亚，外汇储备几乎 ...
