On October 7, 2022, President Joe Biden's announcement of strict export controls on high-tech semiconductors marked a pivotal moment in the evolving relationship between the US and China. These controls, aimed at curbing the flow of advanced technology to China, triggered a new phase often dubbed the "tech war." The battlefront is centered on tech, especially artificial intelligence and quantum computing, which have become the modern-day equivalents of nuclear weapons in the context of a new Cold War. However, the effectiveness of US efforts to hinder China's technological advancement remains uncertain. Trade sanctions alone may not deter China, as evidenced by their limited impact on Russia. Additionally, China's tendency to acquire technology through various means, including intellectual property theft, poses a formidable challenge. This ongoing struggle highlights the complex and evolving nature of global technological competition between these two superpowers.
