US vs. China: The Evolving Tech Stacks in the Era of Trump 2.0

This has allowed American firms to dominate in AI accelerators and military applications. Under Trump 1.0, export controls prevented China from accessing EUV tools, a policy reinforced in Trump 2.0 with threats of 200% tariffs on rare earth magnets critical for chip production.

China, however, has made remarkable strides in self-reliance. Through state-backed giants like SMIC (Semiconductor Manufacturing International Corporation) and Huawei, Beijing has ramped up production of 7nm chips, bypassing some US restrictions via domestic tools and stockpiling. By 2025, China aims to triple AI chip output, with Huawei’s Ascend 910D and Cambricon’s processors supporting native FP8 formats for efficient AI training.

Trump’s recent actions, including lifting the Biden-era ban on Nvidia’s H20 chips to China after negotiations, reflect a pragmatic approach: securing concessions like relaxed rare earth exports in exchange for limited tech access. Going forward, Trump’s proposed 15% commission on US AI chip sales to China could fund domestic fabs under the CHIPS Act, potentially widening the US lead, but risks alienating allies if overzealously applied.

China, meanwhile, is poised to export more mid-tier chips to the Global South, challenging US market share. Artificial Intelligence: Innovation vs. ScaleIn AI, the US tech stack shines in foundational research and model development. Powerhouses like OpenAI, Google DeepMind, and xAI lead with models surpassing 20% accuracy on advanced benchmarks, driven by vast datasets, talent pools, and venture capital ecosystems.

The US benefits from open-source contributions and alliances, such as with the EU and Japan, fostering innovation in areas like multimodal AI and ethical frameworks. Trump’s executive order promoting American AI exports underscores this, positioning the US stack as the “global standard,” akin to the dollar’s dominance. China’s AI stack, bolstered by firms like Baidu, Alibaba, and DeepSeek, excels in rapid scaling and application deployment. With a massive domestic market and government subsidies, China has closed gaps in large language models, achieving 14% benchmark accuracy and integrating AI into surveillance, manufacturing, and e-commerce.

Beijing’s “whole-of-society” approach, including heavy embedding in global open-source communities, has accelerated progress despite US curbs. Under Trump, intensified export controls on AI chips and software could slow China’s momentum, but his administration’s reversal of Biden’s “Diffusion Rule” suggests a focus on competitive dominance rather than blanket restrictions.

Analysts predict Trump will expand entity lists to target affiliates, denying licenses more aggressively, which might force China to innovate domestically but at a higher cost.

By 2030, if Trump prioritizes alliances, the US could maintain a 2-3 year lead; otherwise, China’s scale might dominate emerging markets.

Looking to 6G, China invests heavily in terahertz tech and satellite integration, aiming for ubiquitous connectivity.The US, through companies like Qualcomm and Ericsson (via alliances), dominates standards-setting via bodies like 3GPP, ensuring interoperability and security. Trump’s policies, including bans on Huawei in US networks and pressure on allies, have fragmented global telecom, but his 2025 truce extended tariff pauses in exchange for tech concessions. Future actions may include curbs on Chinese smart cars and connected devices, expanding the “tech wall.”

This could protect US infrastructure but risk isolating American firms if the Global South opts for Huawei’s affordable stack.

Trump’s $1 billion+ AI funding bill, which includes quantum, aims to accelerate US R&D.

In biotech, the US leads in mRNA tech (Moderna, Pfizer), while China dominates in genomics via BGI and rapid drug trials. Trump’s tariffs on Chinese EVs and green tech could extend to biotech imports, fostering US self-reliance.

Electric Vehicles and Green Tech: Market DisruptionChina’s EV stack, led by BYD and CATL, controls 60% of global battery production, emphasizing affordability and supply chain integration. The US, with Tesla and Ford, excels in software and autonomous driving. Trump’s threats of 25% tariffs on Chinese goods could shield US manufacturers but inflate costs.

Trump’s Actions and Future Outlook

By 2030, the US could retain leads in high-end tech if Trump forges alliances, while China’s resilience might erode edges in scale-driven sectors. The rivalry will reshape global supply chains, with Southeast Asia benefiting from diversification. Ultimately, Trump’s actions will determine if the US stack becomes the global benchmark or if bifurcation accelerates.
