The United States and China are intensifying their technological rivalry across three critical sectors: artificial intelligence (AI), semiconductors, and batteries. Recent developments include the US expanding export controls on advanced AI chips to China, while China accelerates domestic production of electric vehicle batteries and AI models.
In May 2026, the Biden administration announced new restrictions on the export of high-bandwidth memory chips used in AI training, affecting companies like NVIDIA and AMD. China responded by increasing state investment in its semiconductor industry, aiming for self-sufficiency by 2030. Meanwhile, Chinese battery manufacturers CATL and BYD continue to dominate global EV battery production, with a combined market share of over 50%.
The rivalry extends to AI applications, where US companies like OpenAI and Google lead in generative AI, but Chinese firms such as Baidu and Alibaba are rapidly catching up with their own large language models. The competition is reshaping global supply chains and prompting both nations to invest billions in research and development.
