美国卡住乙烷，中国却笑出声：这招太小觑了！

Core Viewpoint - The U.S. has restricted ethane exports to China as a retaliatory measure against China's rare earth controls, revealing deeper resource competition dynamics between the two nations [2][3] Group 1: Ethane's Importance and China's Response - Ethane is crucial for producing ethylene, which is essential for plastics, chemicals, and even missiles. China imports 5.53 million tons of ethane from the U.S. annually, accounting for nearly half of U.S. exports [2] - China has diversified its ethylene feedstock sources through various methods, including naphtha cracking, coal-to-olefins, and long-term contracts with Middle Eastern suppliers, effectively mitigating reliance on U.S. ethane [2] Group 2: Domestic Production and Technological Advancements - China is developing its own ethane production capabilities, with projects like PetroChina's 1.2 million ton facility in Ordos set to launch in 2028, utilizing proprietary technology that achieves a 5% higher yield than U.S. methods [3] - Other companies, such as Satellite Chemical and Wanhua Chemical, are also innovating in ethylene production, with significant cost reductions expected by 2030 [3] Group 3: U.S. Market Challenges - The U.S. ethane market is facing significant challenges, including plummeting prices, cash flow issues for shale gas producers, and rising storage costs, leading to environmental concerns [3] - U.S. exporters are struggling as China shifts its focus to Middle Eastern and Russian suppliers, leaving American companies in a vulnerable position [3] Group 4: Broader Implications of Resource Competition - The competition for resource control is fundamentally about power dynamics, with rare earths being vital for high-tech industries and ethane considered a secondary resource for industrial applications [3] - The U.S. strategy of using sanctions and export restrictions may backfire, as China has already established a comprehensive safety net across raw materials, technology, and market access [3]
