U.S. Chip Export Controls Propel China’s AI Ambitions: Huawei Emerges as Key Beneficiary
Introduction
The U.S. government’s recent tightening of export controls on advanced semiconductors, particularly those affecting Nvidia’s AI chips, has inadvertently provided a significant boost to Chinese tech giants like Huawei. Analysts suggest that these restrictions are accelerating China’s efforts to achieve self-reliance in critical technologies, with Huawei poised to fill the void left by U.S. suppliers.
U.S. Chip Export Controls and Their Immediate Impact
In April 2025, the U.S. Department of Commerce expanded its export restrictions, requiring licenses for the sale of Nvidia’s H20 AI chips to China. This move effectively halted the shipment of these high-performance processors, which are crucial for training large-scale AI models. Nvidia, which generated approximately $17 billion in revenue from China in the previous fiscal year, now faces potential losses of up to $5.5 billion in the first quarter alone due to these new regulations.
Huawei’s Strategic Response: Ascend 910C and 920 AI Chips
In response to the U.S. chip export controls, Huawei has accelerated the development and deployment of its own AI chips. The company is preparing to mass-produce the Ascend 910C, an advanced GPU that combines two 910B chips to deliver performance comparable to Nvidia’s H100. Manufactured using a 7nm process by China’s Semiconductor Manufacturing International Corporation (SMIC), the 910C is expected to become the cornerstone of China’s AI infrastructure.
Additionally, Huawei has unveiled the Ascend 920, a next-generation AI chip designed to fill the gap left by Nvidia’s H20. Built on a 6nm process, the Ascend 920 boasts over 900 teraflops of processing power and 4 terabytes per second of memory bandwidth. A variant, the 920C, is optimized for Transformer and Mixture of Experts models, offering 30% to 40% higher efficiency than its predecessor.
Analysts’ Perspectives: A Double-Edged Sword
While the U.S. aims to curb China’s technological advancements through U.S. Chip Export Controls, analysts warn that these measures may have unintended consequences. By restricting access to U.S.-made chips, the U.S. is inadvertently encouraging Chinese firms to innovate and develop indigenous alternatives. This shift could accelerate China’s progress in AI and semiconductor technologies, potentially undermining the U.S.’s long-term strategic interests.
Market Reactions: Nvidia’s Decline and Huawei’s Rise
The market has responded swiftly to these developments. Nvidia’s stock has declined by over 25% since the announcement of the new export controls, reflecting investor concerns about the company’s reduced access to the Chinese market.
Conversely, Huawei’s rapid advancement in AI chip development has positioned it as a viable alternative for Chinese tech companies, potentially capturing a significant share of the domestic market previously dominated by Nvidia.
Conclusion
The U.S.’s expanded chip export controls on advanced semiconductors have created a complex landscape. While intended to hinder China’s technological progress, these measures have spurred Chinese companies like Huawei to accelerate their own innovations. As Huawei prepares to mass-produce its Ascend 910C and 920 AI chips, it stands to become a central player in China’s AI ecosystem, potentially reshaping the global semiconductor industry.
