Core Viewpoint - The recent decision by the U.S. government to suspend the export of large passenger aircraft engines to China is seen as an attempt to hinder China's development of domestic aircraft, but it may inadvertently accelerate China's determination to achieve self-sufficiency in aviation engine technology [1][9]. Group 1: U.S.-China Trade Relations - The U.S. is struggling to respond effectively to China's rare earth export restrictions while simultaneously attempting to cut off engine supplies to China, indicating a lack of effective leverage [3]. - Trump's administration has reinstated high tariffs on Chinese goods, reaching as high as 145%, but China has prepared countermeasures that directly impact U.S. farmers and high-tech industries [5][8]. - The U.S. high-tech sector is facing challenges due to its reliance on Chinese rare earth materials, with production lines for critical military and commercial products being affected [7]. Group 2: China's Aviation Industry Development - China has already tested the CJ-1000A engine, which can replace imported engines, and this engine is expected to significantly reduce costs by approximately 30% compared to imports while enhancing performance [9][11]. - The successful development of military engines like the "Taihang" and "WS-15" signifies a leap in China's military aviation technology, allowing for more competitive offerings in the global market [11]. - China has mastered core technologies for various types of engines, entering a new phase of independence in aviation engine design, which may mitigate short-term impacts from U.S. supply cuts [13]. Group 3: Future Prospects - The C929 project, initially a collaboration with Russia, is now being independently advanced by China, featuring a domestically produced engine with superior thrust compared to competitors [15]. - The maturation of high-thrust engines like the Changjiang-2000 may enable China to develop larger strategic transport aircraft, enhancing its military capabilities [17]. - China's advancements in new power systems, including electric motors and hydrogen fuel engines, position it to lead in future aviation technology, similar to the rapid growth seen in its semiconductor industry following U.S. restrictions [18].
