#USChinaTensions are high due to trade disputes (tariffs, warnings about deals with the US), tech competition (5G, AI, supply chains, IP theft), and security concerns. The US has tariffs up to 145% on some Chinese goods, and China has retaliated. Tech rivalry includes US export controls on semiconductors. A long-standing US-China science and tech agreement is at risk. The competition for global influence is likened to the Cold War. These tensions impact trade, tech, and even global scientific collaboration as companies "de-risk" from China.
