The semiconductor war between the United States and China is a pivotal front in the broader technological and geopolitical rivalry between the two superpowers. Semiconductors, the essential components of almost all modern electronics, are at the heart of this battle, with both countries vying for dominance in chip manufacturing, innovation, and supply chain control. The implications of this conflict stretch across the global tech landscape, disrupting supply chains and reshaping international trade. The origins of the US-China semiconductor war lie in the growing concern in the United States over China’s technological ambitions, particularly its drive to become a leader in advanced technologies like artificial intelligence (AI), 5G, and quantum computing. The Trump administration first imposed restrictions on Chinese technology firms, citing national security risks and fears that China could surpass the US in key technologies. These restrictions, including sanctions on Chinese telecom giant Huawei, severely limited China’s access to critical semiconductor components. The Biden administration has continued this policy, further tightening export controls on semiconductor technology. In 2022, new regulations were introduced, barring US companies from exporting advanced chips and equipment to China without a license. These measures target China’s ambitions in AI, advanced computing, and military technologies, preventing the country from accessing the cutting-edge semiconductors necessary to advance its technological prowess. China, in response, has accelerated its efforts to achieve self-sufficiency in semiconductor production. The country has invested heavily in its domestic semiconductor industry, pouring billions of dollars into research and development and building its own chip manufacturing capabilities. However, despite these efforts, China remains heavily dependent on foreign technology, particularly from the US, Taiwan, and South Korea. The semiconductor war has created significant ripple effects throughout global tech supply chains.
