中方对美芯片发起调查，国际风向开始变了

Core Viewpoint - The Chinese Ministry of Commerce has initiated anti-dumping investigations against American analog chips and anti-discrimination investigations regarding U.S. measures, signaling a strong response to U.S. chip hegemony [1][3]. Group 1: U.S. Actions and Their Impact - The U.S. has previously threatened to ban Huawei chips and imposed restrictions on advanced AI chip sales to China, which has led to a significant decline in NVIDIA's market share in China from 95% to 50% [2][5]. - The U.S. government has also implemented a "chip tax" of 15% on American chip companies operating in China, which has negatively impacted their revenues [5]. Group 2: China's Strategic Response - China has developed three key strategies in response to U.S. actions: 1. Technological Breakthroughs: Following the U.S. ban on H20 chips, Huawei announced the successful development of the Ascend 920 chip, increasing China's AI chip self-sufficiency from 12% to 40% [9]. 2. Market Leverage: U.S. chip companies have significantly reduced prices to compete, resulting in a drastic drop in their profits while China seeks to create a fairer environment for its domestic chip manufacturers through anti-dumping investigations [11]. 3. Rule-Based Countermeasures: China is utilizing the WTO framework to challenge U.S. discriminatory policies, effectively turning the tables on U.S. tactics [11]. Group 3: Broader Implications of the Tech Battle - The ongoing U.S.-China tech rivalry extends beyond chips, with the U.S. facing backlash from its own policies, as evidenced by the agricultural sector's struggles due to reduced Chinese orders for U.S. soybeans [14][16]. - China controls nearly 90% of global refined rare earth production, using this leverage strategically in trade negotiations with the U.S. [16]. - The conflict illustrates that the U.S. approach of weaponizing rules may ultimately backfire, while China's focus on innovation and resilience positions it favorably in the long term [18][20].
