U.S.-China Trade Dynamics and the Future of AI Semiconductor Exports

The U.S.-China semiconductor rivalry has long been a battleground for technological supremacy, but recent shifts in export control policies are reshaping the landscape. As the Trump administration recalibrates its approach to chip exports, investors must grapple with a pivotal question: Will easing restrictions unlock new opportunities for U.S. tech giants like AMD and Nvidia, or will they accelerate China's self-reliance in AI semiconductors? The answer lies in understanding the interplay of policy, innovation, and market dynamics.

The Policy Pendulum: From Restriction to Strategic Flexibility

For years, the U.S. imposed stringent export controls on advanced semiconductors to China, aiming to stifle Beijing's access to AI and supercomputing capabilities. These measures included blacklisting Chinese entities, restricting high-bandwidth chips, and enforcing strict licensing for AI hardware. However, the rescission of the Biden-era AI Diffusion Rule in May 2025 and the Trump administration's emphasis on a “bold, inclusive” AI strategy signal a pivot. The new approach prioritizes collaboration with “trusted allies” while tightening scrutiny on adversarial access, particularly to Chinese AI models.

This shift is not a retreat from containment but a recalibration. The U.S. recognizes that blanket restrictions have unintended consequences: they've driven Chinese firms to innovate, creating alternatives like Huawei's Ascend 910D and RISC-V-based architectures. Meanwhile, U.S. firms like AMD and Nvidia face revenue losses from restricted access to China's $16 billion AI chip market. The administration's recent easing of export controls to Saudi Arabia—facilitating deals like AMD's 500MW AI compute agreement with Humain—demonstrates a strategic focus on diversifying markets while maintaining pressure on China.

U.S. Tech Firms: Navigating Regulatory Headwinds and Innovation

Advanced Micro Devices (AMD) and Nvidia are at the forefront of this transition. AMD's Q2 2025 results highlight the tension between regulatory constraints and market resilience. Despite an $800 million hit from U.S. export restrictions on its MI308 chips to China, AMD reported record revenue of $7.7 billion, driven by strong demand for its EPYC processors and Ryzen CPUs. The company is now pivoting to its MI350 and MI400 series, with the MI355X already outperforming Nvidia's GB200 in token-per-dollar efficiency.

Nvidia, meanwhile, is navigating a complex path. Its H20 chips, downgraded to comply with U.S. restrictions, still account for 12.5% of the company's revenue. However, Chinese firms like ByteDance and Alibaba have spent $16 billion stockpiling these chips, creating a shadow market. The Trump administration's potential approval of new licenses could reignite demand, but Nvidia must also contend with Huawei's CloudMatrix 384 system, which integrates 384 Ascend 910C chips to deliver 300 PFLOPs of raw compute power—nearly double the performance of Nvidia's GB200 NVL72.

Chinese Innovators: Closing the Gap, Expanding the Ecosystem

Huawei's Ascend 910D and CloudMatrix 384 exemplify China's rapid progress. The Ascend 910D, built on SMIC's 7nm N+2 process, delivers 1.2 PFLOPS of FP16 performance and 12% better energy efficiency than Nvidia's H100. While individual chip performance still lags, Huawei's system-level integration and open-sourced Pangu AI models are building a robust ecosystem. The company's 2025 revenue of $369.9 billion underscores its growing influence in AI-as-a-Service (AIaaS) and industry-specific AI deployments.

Yet, Huawei's success is not without challenges. U.S. export controls on EUV lithography machines and etching tools have forced reliance on smuggling and illegal procurement. Huawei's admission of sourcing 2 million logic dies from TSMC in 2024 highlights the fragility of its supply chain. However, the company's investment in full-stack AI solutions—combining hardware, software, and cloud services—positions it to compete globally, even as it grapples with technical hurdles in software ecosystems like CANN and MindSpore.

Investment Opportunities: Balancing Risk and Reward

For investors, the key is to identify firms that can thrive in both a restricted and a more open trade environment. Here are three high-conviction opportunities:

1. AMD (AMD): With its next-gen MI350 and MI400 series, AMD is poised to reclaim market share in AI infrastructure. The company's strategic pivot to the Middle East and its focus on full-stack solutions (e.g., Helios rack-scale AI) mitigate China-related risks. Investors should monitor the U.S. Department of Commerce's licensing decisions and AMD's Q3 2025 guidance.

2. Huawei Technologies: Despite U.S. restrictions, Huawei's ecosystem-driven approach is gaining traction. The company's open-sourced Pangu models and partnerships with Chinese hyperscalers could drive adoption. However, investors must weigh the risks of supply chain vulnerabilities against its long-term R&D investments.

3. Nvidia (NVDA): Nvidia's dominance in AI infrastructure remains unchallenged, but its reliance on the Chinese market creates volatility. The company's recent focus on enterprise and automotive AI (e.g., DRIVE Thor) diversifies its revenue streams. A potential easing of export controls could unlock significant upside, but competition from Huawei's CloudMatrix systems is a wildcard.

The Road Ahead: A New Equilibrium

The U.S.-China semiconductor dynamic is entering a new phase. While export controls will remain a tool of strategic influence, the Trump administration's emphasis on “inclusive” AI collaboration suggests a more nuanced approach. For U.S. firms, this means balancing compliance with innovation; for Chinese players, it means accelerating self-reliance while navigating supply chain constraints.

Investors who position themselves at the intersection of these trends—supporting firms that can adapt to regulatory shifts and technological breakthroughs—stand to benefit from the next chapter in the global AI semiconductor race. The key is to remain agile, as the rules of the game continue to evolve.
